1) Update on Lc analysis - Sooraj Radhakrishan
a. it turns out that the vertex resolution correction is similar for D0 and Lc, which is caused by that distances of tracks to the primary vertices used in the two analyses are similar 
b. will check the TPC and TOF efficiency uncertainty for single tracks to see if there is any room of improvement

2) Run14 J/psi Raa analysis - Rongrong Ma
a. latest checks on luminosity dependence of Jpsi yield are presented. Will update the corresponding material, and back to GPC discussion.
