Geant-4 based PWG4 request for Bi (83/209) +Bi (83/209) collisions at 9.2 GeV. Extra variables are added to the DSTs to apply dphi/dzed differential matching cuts in the TOF.

This is a general-purpose project, includes simulation of the MPD-ECAL (v.3 geometry). Minbias events are generated by UrQMD, light vector meson BR for dielectron decays are enhanced by x20. Decays of short-lived resonances (to have realistic peak widths) and pi0/eta-meson are managed by Pythia8.
The simulation project consists of a few stages:
Events are generated by UrQMD. It should be run with an attached inputfile, which was set up to generate 500 minbias BiBi@9.2 collisions. Some of the particles are requested to be stable in the input file to be further decayed in the mpdroot. Important: The value of ‘rsd’ parameter should be set as a unique integer for each UrQMD run.
Make a fresh check-out of the -dev branch of the MpdRoot, replace:
mcstack/MpdStack.cxx
tof/MpdTofMatchingData.h
tof/MpdTofMatchingData.cxx
gconfig/MpdDecayConfig.txt
files with the attached versions and then compile.
For simulation, please use the attached runMC.C macro.
For reconstruction please use the attached reco.C macro. It produces standard DST files.
Notes:
To validate the production configuration, we need ~ 200,000 events reconstructed for QA.
The output files will have to be copied and stored at NICA cluster.
The ‘mpdroot’ should be tagged for this production.
