HF PWG Meeting Minutes by Zhenyu - 2016/08/04

0) discussion on data production
A. picoDst code
Mustafa reported briefly the status and plan of picoDst code towards official S&C review. There are a couple of things on the to-do list before that: 1) make the vertex selection scheme flexible so that it allows different vertex selection for different data stream 2) remove the vertex error matrix since no one is using it at the moment 

B. Run15 pp/pA pico
Rongrong will ask Jerome whether S&C group will produce the picoDst for us, otherwise we find volunteers from HF PWG

C. Run14 AuAu pico
will follow up with Frank about copying pico from PDSF to RCF

D. pAu centrality definition
PWG will need to find volunteers to work on Run15 pAu data centrality defition. LBNL group does not have the manpower to work on this but will provide guidance.

1) EvtGen Implementation in STAR - Zhenyu
EvtGen is fully implemented in STAR, results from FastSim look reasonble, while test with starsim detector simulation in progress. Difference seen in D+ decay to K-pi+pi- channel between Pythia and EvtGen, leading to a 5-10% efficiency difference for D+ pT=3 GeV/c.
