Hello,

as discussed at today's meeting, I would like to use this official embedding of p+p collisions embedded into MB 2014 Au+Au for our study:

https://drupal.star.bnl.gov/STAR/starsimrequests/2019/jul/18/auau-200-gev-run14-pythia6-dijet-embedding

This large sample is already produced and available at

/star/embed/embedding/AuAu_200_production_2014/Pythia6_pt*_*_*_* (loong list of files)

The simulation was done in several pt_hat bins from 3-5 to 50+ GeV, but I think we can weigh the pt_hat bins by using the PYTHIA cross section for each bin. Also we don't need large statistics at high pT for our purposes. We would then embed single tracks into this sample and the real Au+Au MB data sample and compare the tracking efficiency we obtain. I hope that sounds reasonable.

Thanks,
Robert
