ALEPH_1991_S2435284Hadronic Z decay charged multiplicity measurementExperiment: ALEPH (LEP 1) Spires ID: 2435284 Status: VALIDATED Authors:
The charged particle multiplicity distribution of hadronic Z decays, as measured on the peak of the Z resonance using the ALEPH detector at LEP. The unfolding procedure was model independent, and the distribution was found to have a mean of $20.85 \pm 0.24$, Comparison with lower energy data supports the KNO scaling hypothesis. The shape of the multiplicity distribution is well described by a log-normal distribution, as predicted from a cascading model for multi-particle production. ALEPH_1996_S3196992Measurement of the quark to photon fragmentation functionExperiment: ALEPH (LEP Run 1) Spires ID: 3196992 Status: VALIDATED Authors:
Earlier measurements at LEP of isolated hard photons in hadronic Z decays, attributed to radiation from primary quark pairs, have been extended in the ALEPH experiment to include hard photon production inside hadron jets. Events are selected where all particles combine democratically to form hadron jets, one of which contains a photon with a fractional energy $z > 0.7$. After statistical subtraction of non-prompt photons, the quark-to-photon fragmentation function, $D(z)$, is extracted directly from the measured 2-jet rate.

Transverse momentum distributions at 630 GeV and 1800 GeV based on data from the CDF experiment at the Tevatron collider. CDF_1990_S2089246CDF pseudorapidity distributions at 630 and 1800 GeVExperiment: CDF (Tevatron Run 0) Spires ID: 2089246 Status: VALIDATED Authors:
Pseudorapidity distributions based on the CDF 630 and 1800 GeV runs from 1987. All data is detector corrected. The data confirms the UA5 measurement of a $\d{N}/\d{\eta}$ rise with energy faster than $\ln{\sqrt{s}}$, and as such this analysis is important for constraining the energy evolution of minimum bias and underlying event characteristics in MC simulations.

This is a CDF analysis from run 1, where the distribution of the transverse momentum of W candidates that decay electronically, is measured. The electron is required to be within $\left|\eta\right| < 1.1$, to have a transverse energy of $E_\perp > 20~\GeV$ and a $p_\perp > 12~\GeV$. The neutrino is required to produce a missing energy of $E_{\perp, \text{ miss}}>20~\GeV$. CDF_1994_S2952106CDF Run I color coherence analysis.Experiment: CDF (Tevatron Run 1) Spires ID: 2952106 Status: UNVALIDATED - not functional Authors:
CDF Run I color coherence analysis. Events with $\ge 3$ jets are selected and Et distributions of the three highest-pT jets are obtained. The plotted quantities are the $\Delta{R}$ between the 2nd and 3rd leading jets in the pT and pseudorapidity of the 3rd jet, and $\alpha = \mathrm{d}{\eta}/\mathrm{d}{\phi}$, where $\mathrm{d}{\eta}$ is the pseudorapidity difference between the 2nd and 3rd jets and $\mathrm{d}{\phi}$ is their azimuthal angle difference. Since the data has not been detector-corrected, a bin by bin correction is applied, based on the distributions with ideal and CDF simulation as given in the publication.

Measurement of the differential cross section $\mathrm{d}\sigma/\mathrm{d}E_\perp^j$ for the production of multijet events in ppbar collisions where the sum is over all jets with transverse energy $E_\perp^j > E_\perp^\mathrm{min}$. CDF_2000_S4155203Z pT measurement in CDF Z -> $e^+e^-$ eventsExperiment: CDF (Tevatron Run 1) Spires ID: 4155203 Status: VALIDATED Authors:
Measurement of transverse momentum and total cross section of $e^+e^-$ pairs in the Z-boson region of $66~\text{GeV}/c^2 < m_{ee} < 116~\text{GeV}/c^2$ from pbar-p collisions at sqrt(s) = 1.8 TeV, with the Tevatron CDF detector. The Z pT, in a fully-factorised picture, is generated by the momentum balance against initial state radiation (ISR) and the primordial/intrinsic pT of the Z's parent partons in the incoming hadrons. The Z pT is important in generator tuning to fix the interplay of ISR and multi-parton interactions (MPI) ingenerating `underlying event' activity. This analysis is subject to ambiguities in the experimental Z pT definition, since the Rivet implementation reconstructs the Z momentum from the dileptonpair with finite cones for photon brem summation, rather than YFS/shower unfolding or non-portable direct use of the Z in the event record. CDF_2000_S4266730Differential Dijet Mass Cross SectionExperiment: CDF (Tevatron Run 1) Spires ID: 4266730 Status: UNVALIDATED Authors:

The differential cross section is measured as a function of the transverse energy, $E_\perp$, of a jet in the pseudorapidity region $0.1 < |\eta_1| < 0.7$ for four different pseudorapidity bins of a second jet restricted to $0.1 < |\eta_2| < 3.0$.

CDF_2001_S4751469Field & Stuart Run I underlying event analysis.Experiment: CDF (Tevatron Run 1) Spires ID: 4751469 Status: VALIDATED Authors:
The original CDF underlying event analysis, based on decomposing each event into a transverse structure with ``toward'', ``away'' and ``transverse'' regions defined relative to the azimuthal direction of the leading jet in the event. Since the toward region is by definition dominated by the hard process, as is the away region by momentum balance in the matrix element, the transverse region is most sensitive to multi-parton interactions. The transverse regions occupy $|\phi| \in [60\degree, 120\degree]$ for $|\eta| < 1$. The pT ranges for the leading jet are divided experimentally into the `min-bias' sample from 0--20 GeV, and the `JET20' sample from 18--49 GeV. CDF_2002_S4796047CDF Run 1 charged multiplicity measurementExperiment: CDF (Tevatron Run 1) Spires ID: 4796047 Status: VALIDATED Authors:
A study of ppbar collisions at sqrt(s) = 1800 and 630 GeV collected using a minimum bias trigger in which the data set is divided into two classes corresponding to `soft' and `hard' interactions. For each subsample, the analysis includes measurements of the multiplicity, transverse momentum (pT) spectra, and the average pT and event-by-event pT dispersion as a function of multiplicity. A comparison of results shows distinct differences in the behavior of the two samples as a function of the center of mass energy. The properties of the soft sample are invariant as a function of c.m. energy. CDF_2004_S5839831Transverse cone and 'Swiss cheese' underlying event studiesExperiment: CDF (Tevatron Run 2) Spires ID: 5839831 Status: VALIDATED Authors:
This analysis studies the underlying event via transverse cones of $R = 0.7$ at 90 degrees in \phi relative to the leading (highest E) jet, at sqrt(s) = 630 and 1800 GeV. This is similar to the 2001 CDF UE analysis, except that cones, rather than the whole central \eta range are used. The transverse cones are categorised as TransMIN and TransMAX on an event-by-event basis, to give greater sensitivity to the UE component. 'Swiss Cheese' distributions, where cones around the leading $n$ jets are excluded from the distributions, are also included for $n = 2, 3$. This analysis is useful for constraining the energy evolution of the underlying event, since it performs the same analyses at two distinct CoM energies. WARNING! The pT plots are normalised to raw number of events. The min bias data have not been reproduced by MC, and are not recommended for tuning. CDF_2005_S6080774Differential cross sections for Prompt Diphoton ProductionExperiment: CDF (Tevatron Run 2) Spires ID: 6080774 Status: VALIDATED Authors:

CDF_2007_S7057202CDF Run II inclusive jet cross-section using the kT algorithmExperiment: CDF (Tevatron Run 2) Spires ID: 7057202 Status: UNVALIDATED Authors:
CDF Run II measurement of inclusive jet cross sections at a p-pbar collision energy of 1.96~TeV. Jets are reconstructed in the central part of the detector ($|y|<2.1$) using the kT algorithm with an $R$ parameter of 0.7. The minimum jet pT considered is 54~GeV, with a maximum around 700~GeV. The inclusive jet pT is plotted in bins of rapidity $|y|<0.1$, $0.1<|y|<0.7$, $0.7<|y|<1.1$, $1.1<|y|<1.6$ and $1.6<|y|<2.1$. CDF_2008_LEADINGJETSCDF Run 2 underlying event in leading jet eventsExperiment: CDF (Tevatron Run 2) Spires ID: NONE Status: VALIDATED Authors:
Rick Field's measurement of the underlying event in leading jet events. If the leading jet of the event is within $|\eta| < 2$, the event is accepted and ``toward'', ``away'' and ``transverse'' regions are defined in the same way as in the original (2001) CDF underlying event analysis. The leading jet defines the $\phi$ direction of the toward region. The transverse regions are most sensitive to the underlying event. CDF_2008_NOTE_9351CDF Run 2 underlying event in Drell-YanExperiment: CDF (Tevatron Run 2) Spires ID: NONE Status: VALIDATED Authors:
Deepak Kar and Rick Field's measurement of the underlying event in Drell-Yan events. Z -> ee and Z -> $\mu\mu$ events are selected using a Z mass window cut between 70 and 110 GeV. ``Toward'', ``away'' and ``transverse'' regions are defined in the same way as in the original (2001) CDF underlying event analysis. The reconstructed Z defines the $\phi$ direction of the toward region. The leptons are ignored after the Z has been reconstructed. Thus the region most sensitive to the underlying event is the toward region (the recoil jet is boosted into the away region).

CDF_2008_S7541902Jet pT distributions for 4 jet multiplicity bins as well as the jet multiplicity distribution in W + jets events.Experiment: CDF (Tevatron Run 2) Spires ID: 7541902 Status: UNVALIDATED Authors:
Measurement of the cross section for W boson production in association with jets in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV. The analysis uses 320 pb$^{-1}$ of data collected with the CDF II detector. W bosons are identified in their $e\nu$ decay channel and jets are reconstructed using an $R < 0.4$ cone algorithm. For each $W + \geq$ n-jet sample (where n = 1--4) a measurement of d$\sigma({p}\bar{p} \rightarrow W + \geq$ n jet)/d$E_T(n^{th}$-jet) $\times$ BR($W \rightarrow{e}\nu$) is made, where d$E_T(n^{th}$-jet) is the Et of the n$^{th}$-highest Et jet above 20 GeV. A measurement of the total cross section, $\sigma(p\bar{p} \rightarrow W + \geq$ n-jet) $\times$ BR($W \rightarrow{e}\nu)$ with $E_T(n^{th}-jet) > 25$ GeV is also made. Both measurements are made for jets with $|\eta| < 2$ and for a limited region of the $W \rightarrow{e}\nu$ decay phase space; $|\eta^{e}| < 1.1$, $p_{T}^{e} > 20$ GeV, $p_{T}^{\nu} > 30$ GeV and $M_{T} > 20$ GeV. The cross sections are corrected for all detector effects and can be directly compared to particle level $W$ + jet(s) predictions. These measurements can be used to test and tune QCD predictions for the number of jets in and kinematics of $W$ + jets events. CDF_2008_S7782535CDF Run II b-jet shape paperExperiment: CDF (Tevatron Run 2) Spires ID: 7782535 Status: UNVALIDATED Authors:
A measurement of the shapes of b-jets using 300 pb$^{-1}$ of data obtained with CDF II in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV. The measured quantity is the average integrated jet shape, which is computed over an ensemble of jets. This quantity is expressed as $\Psi(r/R) = \langle\frac{p_T(0 \rightarrow r)}{p_T(0 \rightarrow R)}\rangle$, where pT (0$\rightarrow$r) is the scalar sum of the transverse momenta of all objects inside a sub-cone of radius r around the jet axis. The integrated shapes are by definition normalized such that $\Psi(r/R =1) = 1$. The measurement is done in bins of jet pT in the range 52 to 300 GeV/c. The jets have $|\eta| < 0.7$. The b-jets are expected to be broader than inclusive jets.Moreover, b-jets containing a single b-quark are expected to be narrower than those containing a b bbar pair from gluon splitting.

Measurement of the inclusive jet cross section in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV as a function of jet $E_\perp$, for $E_\perp >$ 62 GeV. The data is collected by the CDF II detector and has an integrated luminosity of 1.13 fb$^{-1}$. The measurement was made using the cone-based Midpoint jet clustering algorithm in rapidity bins within $|y|<2.1$. This measurement can be used to provide increased precision in PDFs at high parton momentum fraction $x$.

Measurement of the b-jet production cross section for events containing a $Z$ boson produced in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV, using data corresponding to an integrated luminosity of 2 fb$^{-1}$ collected by the CDF II detector at the Tevatron. $Z$ bosons are selected in the electron and muon decay modes. Jets are considered with transverse energy $E_T>20$ GeV and pseudorapidity $|\eta|<1.5$. The ratio of the integrated $Z$ + b-jet cross section to the inclusive $Z$ production cross section is measured differentially in jet $E_T$, jet $\eta$, $Z$-boson transverse momentum, number of jets, and number of b-jets. The first two measurements have an entry for each b-jet in the event, the last three measurements have one entry per event.

D0_1996_S3214044Topological distributions of inclusive three- and four-jet eventsExperiment: D0 (Tevatron Run 1) Spires ID: 3214044 Status: UNVALIDATED - currently wrong jet algorithm! Authors:
The global topologies of inclusive three- and four-jet events produced in pbar p interactions are described. The three- and four-jet events are selected from data recorded by the D0 detector at the Fermilab Tevatron Collider operating at a center-of-mass energy of $\sqrt{s}$=1800 GeV. The studies also show that the topological distributions of the different subprocesses involving different numbers of quarks are very similar and reproduce the measured distributions well. The parton-shower Monte Carlo generators provide a less satisfactory description of the topologies of the three- and four-jet events.

Isolated direct photons are probes of pQCD via the annihilation (q qbar -> gamma g) and quark-gluon Compton scattering (q g -> gamma q) processes, the latter of which is also sensitive to the gluon PDF.

The process p pbar -> photon + jet + X as studied by the D0 detector at the Fermilab Tevatron collider at center-of-mass energy sqrt(s) = 1.96 TeV. Photons are reconstructed in the central rapidity region $|y_\gamma| < 1.0$ with transverse momenta in the range 30--400 GeV, while jets are reconstructed in either the central $|y_jet| < 0.8$ or forward $1.5 < |y_\text{jet}| < 2.5$ rapidity intervals with $pT^\text{jet} > 15~\text{GeV}$. The differential cross section $\mathrm{d}^3 \sigma / \mathrm{d}{pT^\gamma} \mathrm{d}{y_\gamma} \mathrm{d}{y_\text{jet}}$ is measured as a function of $pT^\gamma$ in four regions, differing by the relative orientations of the photon and the jet. MC predictions have trouble with simultaneously describing the measured normalization and $pT^\gamma$ dependence of the cross section in any of the four measured regions.

Measurement of the electron charge asymmetry in $p \bar p \to W + X \to e \nu_e + X$ events at a center of mass energy of 1.96 TeV. The asymmetry is measured as a function of the electron transverse momentum and pseudorapidity in the interval (-3.2, 3.2). This data is sensitive to proton parton distribution functions due to the valence asymmetry in the incoming quarks which produce the W. Initial state radiation should also affect the pT distribution.

D0_2009_S8349509Z+jets angular distributionsExperiment: D0 (Tevatron Run 2) Spires ID: 8349509 Status: VALIDATED Authors:
First measurements at a hadron collider of differential cross sections for $Z$+jet+X production in $\Delta\phi(Z, j)$, $|\Delta y(Z, j)|$ and $|y_\mathrm{boost}(Z, j)|$. Vector boson production in association with jets is an excellent probe of QCD and constitutes the main background to many small cross section processes, such as associated Higgs production. These measurements are crucial tests of the predictions of perturbative QCD and current event generators, which have varied success in describing the data. Using these measurements as inputs in tuning event generators will increase the experimental sensitivity to rare signals. D0_2010_S8566488Dijet invariant massExperiment: D0 (Tevatron Run 2) Spires ID: 8566488 Status: UNVALIDATED Authors:
The inclusive dijet production double differential cross section as a function of the dijet invariant mass and of the largest absolute rapidity ($|y|_\text{max}$) of the two jets with the largest transverse momentum in an event is measured using 0.7 fb$^{-1}$ of data. The measurement is performed in six rapidity regions up to $|y|_\text{max}=2.4$. DELPHI_1995_S3137023Strange baryon production in Z hadronic decays at DelphiExperiment: DELPHI (LEP 1) Spires ID: 3137023 Status: VALIDATED Authors:

DELPHI_1996_S3430090Delphi MC tuning on event shapes and identified particles.Experiment: DELPHI (LEP 1) Spires ID: 3430090 Status: VALIDATED Authors:
Event shape and charged particle inclusive distributions measured using 750000 decays of Z bosons to hadrons from the DELPHI detector at LEP. This data, combined with identified particle distributions from all LEP experiments, was used for tuning of shower-hadronisation event generators by the original PROFESSOR method. This is a critical analysis for MC event generator tuning of final state radiation and both flavour and kinematic aspects of hadronisation models.

This analysis is a demonstration of the Rivet analysis structure and functionality: booking histograms; the initialisation, analysis and finalisation phases; and a simple loop over event particles. It has no physical meaning, but can be used as a simple pedagogical template for writing real analyses. H1_1994_S2919893H1 energy flow and charged particle spectra in DISExperiment: H1 (HERA) Spires ID: 2919893 Status: VALIDATED Authors:
Global properties of the hadronic final state in deep inelastic scattering events at HERA are investigated. The data are corrected for detector effects. Energy flows in both the laboratory frame and the hadronic centre of mass system, and energy-energy correlations in the laboratory frame are presented. Historically, the Ariadne colour dipole model provided the only satisfactory description of this data, hence making it a useful 'target' analysis for MC shower models. H1_1995_S3167097Transverse energy and forward jet production in the low x regime at H1Experiment: H1 (HERA Run I) Spires ID: 3167097 Status: UNVALIDATED Authors:
DIS events at low x may be sensitive to new QCD dynamics such as BFKL or CCFM radiation. In particular, BFKL is expected to produce more radiation at high transverse energy in the rapidity span between the proton remnant and the struck quark jet. Performing a transverse energy sum in bins of x and $\eta$ may distinguish between DGLAP and BFKL evolution. H1_2000_S4129130H1 energy flow in DISExperiment: H1 (HERA) Spires ID: 4129130 Status: VALIDATED Authors:
Measurements of transverse energy flow for neutral current deep- inelastic scattering events produced in positron-proton collisions at HERA. The kinematic range covers squared momentum transfers $Q^2$ from 3.2 to 2200 GeV$^2$; the Bjorken scaling variable $x$ from $8 \times 10^{-5}$ to 0.11 and the hadronic mass $W$ from 66 to 233 GeV. The transverse energy flow is measured in the hadronic centre of mass frame and is studied as a function of $Q^2$, $x$, $W$ and pseudorapidity. The behaviour of the mean transverse energy in the central pseudorapidity region and an interval corresponding to the photon fragmentation region are analysed as a function of $Q^2$ and $W$. This analysis is useful for exploring the effect of photon PDFs and for tuning models of parton evolution and treatment of fragmentation and the proton remnant in DIS.

Rick Field's measurement of the underlying event in leading jet events, extended to the LHC. As usual, the leading jet of the defines an azimuthal toward/transverse/away decomposition, in this case the event is accepted within $|\eta| < 2$, as in the CDF 2008 version of the analysis. Since this isn't the Tevatron, I've chosen to use $k_\perp$ rather than midpoint jets.

Modification of the MC leading jets underlying event analysis to study the UE in hard photon+jet events. This may be of interest, because the leading QCD dipole structure is different from that in either dijet or Drell-Yan hard processes.

Correlation in $\eta$ and $\phi$ between the charged hadron with the highest pT (``trigger particle'') and the other charged hadrons in the event (``associated particles''). The data was collected in d-Au collisions at 200 GeV. Nevertheless, it is very proton-proton like and can therefore be compared to pp Monte Carlo (not for tuning, but for qualitative studies.) STAR_2009_UE_HELENUE measurement in pp at 200 GeVExperiment: STAR (RHIC pp 200 GeV) Spires ID: None Status: VALIDATED -- but PRELIMINARY DATA! Authors:
UE analysis similar to Rick Field's leading jet analysis. SIScone with radius/resolution parameter R=0.7 is used. Particles with $pT > 0.2~\text{GeV}$ and $|\eta| < 1$ are included in the analysis. All particles are assumed to have zero mass. Only jets with neutral energy $< 0.7$ are included. For the transMIN and transMAX $\Delta(\phi)$ is between $\pi/3$ and $2\pi/3$, and $\Delta(\eta) < 2.0$. For the jet region the area of the jet is used for the normalization, i.e. the scaling factor is $\pi R^2$ and not $\mathrm{d}\phi\mathrm{d}\eta$ (this is different from what Rick Field does!). The tracking efficiency is $\sim 0.8$, but that is an approximation, as below $pT \sim 0.6~\text{GeV}$ it is falling quite steeply.

This study comprises measurements of pseudorapidity distributions measured with the UA5 detector at 200 and 900 GeV center of momentum energy.

UA5_1988_S1867512Charged particle correlations in ppbar non-single-diffractive events of the UA5 detector at sqrt(s) = 200, 546 and 900 GeV.Experiment: UA5 (CERN SPS) Spires ID: 1867512 Status: UNVALIDATED Authors:
Data on two-particle pseudorapidity and multiplicity correlations of charged particles for non single-diffractive $\bar{p}p$ collisions at c.m. energies of 200, 546 and 900 GeV. Pseudorapidity correlations interpreted in terms of a cluster model, which has been motivated by this and other experiments, require on average about two charged particles per cluster. The decay width of the clusters in pseudorapidity is approximately independent of multiplicity and of c.m. energy. The investigations of correlations in terms of pseudorapidity gaps confirm the picture of cluster production. The strength of forward-backward multiplicity correlations increases linearly with ins and depends strongly on position and size of the pseudorapidity gap separating the forward and backward interval. All our correlation studies can be understood in terms of a cluster model in which clusters contain on average about two charged particles, i.e. are of similar magnitude to earlier estimates from the ISR. UA5_1989_S1926373UA5 charged multiplicity measurementsExperiment: UA5 (CERN SPS) Spires ID: 1926373 Status: VALIDATED Authors:
Multiplicity distributions of charged particles produced in non single-diffractive collisions between protons and antiprotons at centre of mass energies of 200 and 900 GeV are presented. The data were recorded in the UA5 streamer chambers at the CERN Collider, which was operated in a pulsed mode between the two energies. A new method to correct for acceptance limitations and inefficiencies based on the principle of maximum entropy has been used. Multiplicity distributions in full phase space and in intervals of pseudorapidity are presented in tabular form. The violation of KNO scaling in full phase space found by the UA5 group at an energy of 546 GeV is confirmed also at 200 and 900 GeV. The shape of the 900 GeV distribution in full phase space is narrower in the peak region than at 200 GeV but exhibits a pronounced high multiplicity tail. The negative binomial distribution fits data at 200 GeV in all pseudorapidity intervals and in small intervals at 900 GeV. In large intervals at 900 GeV, however, the negative binomial distribution. Fits to the partially coherent laser distribution are also presented as well as comparisons with predictions of the Dual Parton, the Fritiof and the Pythia models. ZEUS_2001_S4815815Dijet photoproduction analysisExperiment: ZEUS (HERA Run I) Spires ID: 4815815 Status: UNVALIDATED Authors:
ZEUS photoproduction of jets from proton-positron collisions at beam energies of 820~GeV on 27.5~GeV. Photoproduction can either be direct, in which case the photon interacts directly with the parton, or resolved, in which case the photon acts as a source of quarks and gluons. A photon-proton centre of mass energy of between 134~GeV and 227~GeV is probed, with values of xP, the fractional momentum of the partons inside the proton, predominantly in the region between 0.01 and 0.1. The fractional momentum of the partons from the photon, $x\gamma$, is in the region 0.1 to 1. Jets are reconstructed in the range $-1<|\eta|<2.4$ using the kT algorithm with an R parameter of 1.0. The minimum pT of the leading jet should be greater then 14~GeV, and at least one other jet must have pT$>$11~GeV. |
