Hi all,
I try to do fast simulation with this decay chain: pbp->Ds+ Ds-; Ds- ->K+K-pi-; Ds+ ->e+ nv eta; eta->pi+pi-pi0 (gamma gamma). From the examples in macro/scrut, I got some problems for simulating the neutral channel:
1) in simulation macro:
// generate electro-magnetic / hadronic split offs in the EMC? switch off when running w/o EMC
Bool_t enableSplitoff = kFALSE;
//enable the producting of parametrized neutral (hadronic) split offs
if (enableSplitoff)
fastSim->EnableSplitoffs(BaseDir+"/fsim/splitpars.dat");
From the comments there, if I understand correctly, the "enableSplitoff" seems should be switched on for eta->pi+pi-pi0 (gamma gamma). I tried kTRUE, but it crashed.
2) in analysis:
// *** name of the only PidAlgo TClonesArray in fsim
TString pidalg = "PidChargedProbability";
Does it mean no neutral algorithm in fast simulation? then, how to fill the neutral list?
Thanks in advance.
Lu
