EEmc Gammas via conversion method, systematics II

Abstract: The EEmc Gammas via conversion method for extracting single photons should, in principle, have easily quantified systematic uncertainties.  One needs to know only two things -- the efficiency with which the signal and background pass the analyzing cut.  In practice, since we have three sources of background, the systematic uncertainties become more complicated.  We perform an extraction of the gamma yields vs pT, and determine the systematic uncertainties due to the measured efficiencies.

0.0 Data Sample and Cuts

 
Event sample:
 
1. Data from ppLong2
2. All fills after L2gamma EEmc elevated to physics
4. Select trigger ID 137641
 
Cuts:
 
Before extraction:
1. Require candidate to be w/in the EEMC with pT > 5.0 GeV.
2. Isolation cut -- ET / ETR<0.3 > 0.9
3. Charged particle veto -- require sum of all preshower-1 tiles w/in R < 0.3 to be == 0
4. Analyzing cut -- sum preshower-2 tiles w/in R < 0.3 is greater than zero (i.e. at least one tile w/ ADC > 3 sigma + ped).
 
Post Extraction:
5. Extracted yields summed over -8 < D < -2.

EEmc Gammas via conversion method, determine/cross check efficiencies

Abstract:  In order to use the conversion method, we need to know the efficiencies with which single photons and the different sources of background candidates pass the analyzing cut.  So far we have identified two sources of backgrounds: (1) photonic backgrounds arising from the decay of mesons, e.g. pi0 --> gamma gamma, and (2) neutral hadrons (or charged hadrons which pass the CPV) which hadronize w/in the calorimeter stack.  We should be able to estimate the efficiencies for both of these directly from the data with good precision.  The only parameter in his method which relies on the Monte Carlo is the probability for a single photon to convert in the 1st radiator of the EEmc.
