This is a first attempt at comparing the performance of the CAL shower shape analysis between pass7 and pass8.
The file used for the work are:
For Pass7:
AG-GR-v17r31-StdCuts-merit.root
BKG-GR-v17r31-StdCuts-merit.root
where StdCuts are: FswGamState == 0&& CalEnergyRaw> 5&& TkrNumTracks> 0&& CalCsIRLn> 4.
For Pass8:
AG-GR-v20r3p4-OVL
BKG-GR-v20r3p4-OVL
I include the following precuts to the allGamma sample for both Pass7 and Pass8:
FswGamState==0 && TkrNumTracks > 0 && (CalEnergyRaw > 5 && CalCsIRLn > 4) && CTBCPFGamProb>0
note for Pass8 CalEnergyRaw is substutited by CalUberEnergy and I have added the cut on CTBCPFGamProb because it is necessary that the sample of events pass the
Cpf selection before I can compare the Pass7 and Pass8 selection in the CAL.
To the BKG sample I include in addition to the above selection the condition that there not be gamma's in the sample, i.e. a cut on
McSourceId != 7000
The selection conditions assigned to each node are defined below:
veto BackSeal: ((Cal67Sum - 66.)/33.5)^2 + ((Cal67Diff + .4)/7.2)^2 < 1.2 & CalLLRms < 30
veto LowE: CalEdgeEnergy>0 & CalEdgeEnergyRatio > (LogCalEnergyRaw -.5)/2.
filter VTXSplit: VtxAngle > 0
veto VtxSideSeal: (CalDeltaEdgeEnergy < .6 & CalDeltaEdgeEnergy < 6/CalEdgeEnergy & CalEdgeEnergy < 190)
veto Vtx: (CTBTkrCoreCalDoca<32.3 | (CTBTkrCoreCalDoca<152 & XtalRmsTkrCoreDoca<-10)) & XtalRmsTkrCoreDoca < (2- .15*CTBTkrCoreCalDoca) & Tkr1CoreHC > 0
filter notVTXSplit: VtxAngle == 0
veto TkrSideSeal: (CalDeltaEdgeEnergy < .75 | (CalDeltaEdgeEnergy < .95 - (30./(CalEdgeEnergy+20))^2 & CalEdgeEnergy < 300)) & CalDeltaEdgeEnergy < (1.1 - CalEdgeEnergy/200)
filter nTkrFront: TkrNumTracks > 1 && Tkr1FirstLayer < 5 &&(CTBTkrCoreCalDoca<40.56 | (CalXtalRatio<0.105 & EvtECalTransRms<3.45))
filter nTkrBack: "TkrNumTracks > 1 && Tkr1FirstLayer > 5 && ((CTBTkrSHRCalAngle>0.142 && CTBTkrCoreCalDoca<16.7) | (CTBTkrSHRCalAngle<0.142 & XtalRmsTkrCoreDoca<-15.4))
filter 1TkrFront: (TkrNumTracks == 1) && Tkr1FirstLayer < 5 && (EvtECalTrackDoca < 2.13 || CTBTkrEnergyFrac > 0.285)
filter 1TkrBack: (TkrNumTracks == 1) && Tkr1FirstLayer > 5 && !(XtalRmsTkrCoreDoca > -3 && CalTrkXtalRmsE > 12)
Below are some plots on the sequential selection efficiency for each node in the CAL worksheet, I apologize for the low contrast yellow line in the plots!
