Here I duplicate the large Monte Carlo simulation request. This is a Geant4 based general-purpose project, which includes simulation of the MPD-ECAL (v.3 geometry) and has enhanced (x20) probabilities for light vector meson decays to ee+X channels. Since original branching for such decays is 10^-4-10^-5, the enhancement does not affect the simulation of hadrons. The general idea is to use this simulation for analysis updates towards the DAC meeting.
The simulation project consists of a few stages:

  1. Events are generated by UrQMD. It should be run with an attached inputfile, which was setup to generate 500 minbias AuAu@11 collisions. Some of the particles are requested to be stable in the input file to be further decayed by Geant.
    Important: The value of ‘rsd’ parameter should be set as a unique integer for each UrQMD run.
  2. Make a fresh check-out of the dev version of the mpdroot, then compile it. Replace mpdroot/gconfig/UserDecay.C file with the attached file. The file redefines decay channels for eta/rho/omega/phi/eta’
  3. For simulation, please use attached runMC.C macro.
  4. For reconstruction please use attached reco.C macro. It produced standard DST files and filtered microDST files.

That’s really it. The full chain of simulation takes about 20 hours for 500 events. To simulate 10M events one would need ~ 10 days/2000 CPUs.
