SMD Band Structure - Tower Energy Correlation
Updated on Mon, 2008-04-07 16:44. Originally created by wleight on 2008-04-07 14:49.To examine whether or not the appearance of band structure in the SMD response was correlated to the response of the towers overlapping with a given SMD strip, I filled a histogram of BSMDE strip i

List of systematic studies for gammas
Updated on Thu, 2008-06-12 13:09. Originally created by jwebb on 2008-04-05 16:11.This blog entry will be used to collect ideas which I happen to think of for systematic studies for gammas.

(in progress) EEmc Gammas via conversion method, yield estimates for 2009
Updated on Sat, 2008-04-05 13:32. Originally created by jwebb on 2008-03-31 18:32.Abstract: We estimate the event yields which may be obtained using the conversion method in the 2009 run.
1.0 Event 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 (CPV) -- 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).
After extraction:
5. Require -8 < log(Epost/Esmd) < -2
2.0 Monte Carlo
Event Sample
1. 125k Single gammas w/ 2006 geometry
2. 125k Single gammas w/ 2009 geometry
3. Thrown w/ vertex width of +/- 30cm
4. Thrown w/ eta range 0.8 to 2.2
5. Thrown w/ 4 muons in event to establish vertex. Muons thrown w/ eta = -0.25.
6. pT sampled from e^{-0.6} distribution for pT > 5.0 GeV.
Analysis:
MuDsts are created from the MC events, and gamma trees are created. Events are subjected to same analysis cuts as in section 1.0 above.
