 1) J/psi polarization in Run15 pp/A (MTD) - Zhen Liu
a. For some pT bins, the fitting range stops at the middle of a cos(theta) bin. Need to be fixed.
b. Check the raw signal extraction for some cos(theta) bins at the edge
c. The results with pT>1.3 GeV/c and 0.2 bin width are consistent with published and preliminary results. However, there are tensions between pT > 1.3 and pT > 1.5 GeV/c results. Need to further investigate this.
d. For pAu results, the raw count distribution in 0-1 GeV/c bin looks a bit weird. Need to check the signal extraction.
