The SISCone Jet Algorithm

Version 2.0.1

SISCone is a Seedless Infrared Safe Cone jet algorithm.

It was developped by Gavin Salam and Gregory Soyez. It is available as a library, as a standalone program or as a FastJet (>= 2.1) plugin.

News (May 29th 2009): We have released a new version of SISCone (v2.0.1). See the release notes for a short description of what is new in this version. It mostly consists of bug-fixes related to compilation issues, the most important one being that shared libraries are now built by default. This version will be available in the forthcoming release of FastJet (v2.4.1).

News (April 17th 2009): We have released a new version of SISCone (v2.0.0). The main improvement is that SISCone now includes an implementation in spherical coordinates allowing one to cluster e+e- events. This version is available with FastJet(>=2.4.0).

The algorithm is described in the publication JHEP 05 (2007) 086 [arXiv:0704.0292 [hep-ph]]. See the links below for more detailed information.
