1) Update on the D+- in Au+Au@200GeV - Jan Vanek
With use of TMWA was able to push down to lower pt. Now used the same pt-binning as D0.
Now the lowest pt bin (1GeV to 1.5GeV) has 10sigma.
Cannot get lower due to cut pt>300 - this could be changed.

2) MTD matching efficiency study in Run15 - RongRong Ma
Similar procedure followed as for run14 with couple improvements.
Results and final systematical errors are consistent with run 14 - good.

3) NPE v2 in 54 GeV Au+Au - Yuanjing Ji
Currently cannot get reliable electron purity from dE/dx in the region of crossing bands.
as there are "ghost" from TOF. It was suggested to try to estimate the admixture from the
shape of 1/beta distribution.

Needs embedding done soon. Sofa using purity from run9/10.

4) Update on Upsilon ->nu+nu in Au+Au - Pengfei Wang
Was suggested to try the CEM calculation curve as one way to fit.
