single D0's with long ctau

For some studies, I have generated with starsim 10k D0's (1D0 per event) with power law pt (in 0<pT<5) but with a larger timelife :

time dependent gain correction by LED events

Based on the original time dependent correction scheme, I tried a slightly different way to calculate "gcorr" for a given event.

Quick PT bin look at run 11

 There are three different PT bins: 2-10, 10-13, and 13-17. There are two plots for each bin; the first is the complete fit including the eta meson peak.

Small Simulation: Endcap Energy Change

Here I show the effect that increasing the energy the jet finder sees in the endcap has on the jet pt and eta spectra.

 

Embedding Distribution for Run 9 pp 500

In order to properly ensure our embedded simulation request works properly, we examine the distributions of various quantities.

BeamLine for pp500 from TPC Twist

The TPC Twist calibration involves using vertices reconstructed by the TPC, and the current practice is to compare the vertices re

Vetting the ideal simulations for TPC alignment studies

I wanted to be sure that the simulations we're making for TPC alignment residual studies was really doing what we want it to do...

 

Log files have this output:

EMC jet-like studies

For data simulation comparison:

FMS pi^{0} pt>2.0GeV/c and BEMC(EEMC) 1.0GeV/c<pt<2.0GeV/c

For jet-like and underlying comparison:
