Improvements of Starlight MC interface for passing generated events to Pythia8 for QED shower

Mateusz Dyndal requested to merge (removed):21.6-16 into 21.6

Several improvements to Starlight_i interface:

  • New function bool Starlight_i::starlight2lhef() which creates appropriate (temporary) LHEF event format file which can be then read by Pythia8
  • declareProperty("lheOutput", m_lheOutput) variable
 steers the setup (false (def) =original use of HepMC format, true = dump events to LHE file)

Testjob outputs for excpusive dimuon production in Pb+Pb are available at: /afs/cern.ch/user/m/mdyndal/public/Py8Starlight_mumu_10k.EVNT.pool.root /afs/cern.ch/user/m/mdyndal/public/DAOD_TRUTH3.tutorial.pool.root

Some validation plots showing (expected) broadening of dimuon acoplanarity are attached, along with the example JO. ha Screenshot_2020-07-10_at_14.50.01 MC15.420256.Py8Starlight_gammagamma2mumu_breakupMode5_4M.py
