Comparison of conversion rates in MC to data, take 1
Updated on Wed, 2009-06-10 12:18. Originally created by jwebb on 2009-06-09 12:23.
Abstract: We compare the conversion rate for simulated π0 events in the 1st radiator of the endcap to data. We find a conversion rate of 90% +/- 2% for the simulation, compared with 91.5% +/- 0.3% for the data, where we count any signal w/in R<0.3 of the pion candidate as a conversion.

2009 BSMD Status for 500 GeV Run
Updated on Wed, 2009-09-02 13:44. Originally created by wleight on 2009-06-08 20:50.The BSMD status analysis for the 500 GeV data proceeds in two steps. First, each strip is assigned a status for the whole run from an analysis of fills 10399, 10402, 10403, 10404, 10407, 1041
ZDC simulation with enhanced resoluton
Updated on Mon, 2009-06-08 15:10. Originally created by nkellams on 2009-06-08 15:09.I changed the simulation to be able to read out each SMD strip individually so there are 21 by 32 bins instead of 7 by 8. This required a new binning configuration so I created two; one

Updated on Sun, 2009-06-07 15:41. Originally created by jwebb on 2009-06-07 13:09.Abstract: We examine pi0 invariant mass spectra from the 2006 run, using isolated pions with no energy deposited in the 1st preshower layer w/in a radius of 0.3. An invariant mass of 139.0 +/- 0.3 MeV is reconstruced, with no observed dependence on pseudorapidity. Conversion rates observed by the preshower layers for identified pi0 decays, indicate that, on average, there are three photons w/in the cluster used to measure the energy of the pion.

dAu east-west DCA asymmetry
Updated on Fri, 2009-06-05 17:01. Originally created by genevb on 2009-06-05 17:01.Looking at the signed DCA of tracks on the east half of the TPC minus the west half of the TPC for Run 8 dAu data gives the following results using the calibrations for SpaceCharge and GridLeak ins
