Monte Carlo event generator for quantum black hole production and decay in proton-proton collisions

This page describes the Monte Carlo event generator for quantum black hole production and decay in proton-proton collissions — QBH version 1.02.

Description of Generator

Quantum black holes are produced in proton-proton collisions and decay to two-particle final states. Electric charge, QCD colour, and spin are conserved, while baryon and lepton number need not be conserved. PYTHIA 8 is used for the initial- and final-state radiation, multiple interactions, final state parton showers, fragmentation, and decay processes. The QBH generator interaces to PYTHIA 8 using the Les Houches accord (LHA).

Installation

The QBH generator is written entirely in C++. It interfaces only to PYTHIA 8. If the LHAPDF parton densities are required the LHAPDF libary must be linked. The generator has been tested with PYTHIA version 8.130 and LHAPDF version 5.3.0.

ChangeLog

• version 1.00 - initial version.
• version 1.01 - fixed antineutrinos being added to event record for Majorana neutrinos.
• version 1.02 - fixed spin couting in branching fractions.
