1) Toy MC study for J/psi polarization - Rongrong Ma
redo the study using the values extracted from data
scan lambda_phi in finer bins at lambda_theta=0.75

2) J/psi polarization in Run15 pp 200 GeV - Zhen Liu
simultaneous fit to extract Lambda_theta and Lambda_phi, and get Lambda_inv by considering the covariant matrix 
revisit mean/stat/syst uncertainties calculation 

3) Trigger bias study for jpsi events for Run15 pAu200 - Takahito Todoroki
slide 12: PHOBOS compared their dAu data vs dAu Hijing and saw similar discrepancy
slide 13: don't understand why average multiplicity is close between VPDE and VPDW (table), but the efficiency is different (figure). Will compare the distributions of the particle multiplicity, momentum and species between VPDE/W
