Dear Colleagues,

Thank you for agreeing to serve on this important task force and thank Petr for chairing it. The task force will consist of the following members:

Petr Chaloupka - Chair

Yuri Fisyak

Lokesh Kumar

Grigory Nigmatkulov

Fuqiang Wang

Guannan Xie

Jason Webb (ex. officio)

Gene van Buren (ex. officio)

Xianglei Zhu (ex. officio)

With PWG Helpers:

• LFSUPC: Hui Liu (CCNU), Zach Sweger (UCD)
• JetCorr: David Stewart (Yale), Diptanil Roy (Rutgers), Robert Licenik (NPI)
• HF: Pavol Federic (CTU)
• FCV: Brian Chan (UCLA)
• Spin: TBD (will add this colleague in once we have the name)

The charges to the task force are:

1. Conduct systematic studies on the TPC single track efficiency uncertainty on a few standard datasets, e.g. AuAu200, BES, pp200 or 500 GeV etc. It will be preferred that the uncertainty can be evaluated more differentially in pT, eta/y, luminosity etc when statistics allows.

2. Investigate on any possible improvement in the TPC simulator to improve the efficiency uncertainty, especially for the BES-II datasets.
3. Expect a report from the task force (to be released as a STAR note) The report should include the above studies, as well as a description on standard procedures to evaluate the tracking efficiency uncertainty for other datasets.
4. Timeline:  about 6 months - 1 year. If the full efforts are expected to take longer than this, we expect a preliminary report focusing on the findings from 1) to be released in about 6 months.

Please use this mailing list:  star-tf-trkeff-l AT lists.bnl.gov for task force discussions. You should have received the invitations to subscribe to this mailing list. Let me know if you have any issues.

Once again, thank you for helping on this task force. Should you have any comments/suggestions, please feel free to contact the management team. We look forward to a timely outcome from the task force.

Thanks and Best Regards

Xin for the STAR Management
