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:

JP1 & JP2 Turn on efficiency

I used the 2006 MuDsts to generate the turn on curves for the JP1 and JP2 triggers. Both plots are integrated over all jet patches.

Concerning the 'floating' mass peak and Zgg

 Objective:

Explore the pt-dependent mean mass position in data and MC and perhaps draw some conclusions about the quality of our simulations.
