2008 Electron E/p

I took the runs we had produced from the 2008 pp run (I only found 138 runs of the 191 we asked for).

An initial look at how vertex code effects dAu collisions

Code for running Minuit with PCTs removed is at:

/star/data05/scratch/rjreed/PPV2008Eval/VertexdAuMinuitPCT

 

Run in stardev with:

PPV on steroids evaluated for one file

Code is at: /star/data05/scratch/rjreed/PPV2008Eval/VertexJan/

Run in stardev with options:

Hi all,

QA for run 8 production_dAu (produced w/MinuitVF)

I did some QA for run VIII dAu production trying to evaluate how good is the Minuit vertex finder in dAu.

Compare to Marco's QA for previous years:

mcasym-qg

mcasym-gg

Monte Carlo Asymmetries

Here are the asymmetries for STD, ZERO, GS-C, and MIN that I get out of PYTHIA with the minbias trigger condition applied:

Figure 1: raw minbias asymmetries

and here’s what I get after applying the pT reweighting:

Figure 2: minbias asymmetries after reweighting jet pT spectrum

Figure 3: jetpatch asymmetries

Figure 4: difference between Figures 3 and 1

Figure 5: difference between Figures 3 and 2

Finally, these four plots show the effect of the minbias pT reweighting on the bias systematic for each scenario:
