The STAR experiment

This page will describe in detail the STAR analysis scenario as it was in ~2006.  This scenario involves SUMS grid job submission at RCF through condor-g to PDSF using SRM's at both ends to trans

1. QA for BJP0 trigger and runlist generation
2. Confirm vertex and nSigma cuts with systematic studies
3. Run over new PYTHIA simulation, make basic data/simu comparisons
4. Trigger Bias studies
5. Extract A_TT from transverse data
6. Randomized spin pattern studies
7. PID background estimation

Notes

• Adding the L2gamma trigger would improve statistics but we don't have an officially sanctioned simulation of that trigger available yet.
• This checklist assumes the preliminary result is an inclusive measurement using only Run 6 data; other possibilities are to combine Runs 5 and 6 or to pursue the jet+pion measurement.

Introduction

Lambda/K0S ratio: The Lambda/K0S ratio in Year 2 and Year 4 Au+Au @ 200 GeV. The data to the left of the vertical line comes from Year 2, the data to the right from Year 4.

v2 fluctuations: The yellow shaded region shows the range of allowed values for the width of the v2 distribution divided by the mean of the distribution.
