HF PWG Meeting Minutes by Zhenyu - 2016/04/14

1) sQM plan - Wangmei
PAs (Shuai, Wangmei) are encouraged to report their analysis details at HF PWG meetings. Suggested to calculate and eliminate the possibility that two collisions recorded in a single event, one responsible for MB trigger, the other for UPC Jpsi production. 

2) Jpsi polarization in Run12 pp200 - Siwei
Slide 9/10, suggested to check the (US, LS, US-LS) invmass spectra for each costheta and phi bin, in order to make sure the LS can reproduce the combinatorial background. Fitting the US with crystal ball and polynomial will address the concern.
