1) Introduction of D0 correlated v2 study - Leon
Page 4, check unreasonable statistic fluctuations
Page 9, there are some discussions about how to correct acceptance for D0, also there are suggestions to look at correction for different pT
Page 11, suggest to look at narrower signal region in the future
Page 12, need more check as indicated by Liang
2) vertex refitting - Liang
Page 3, there are a lot of discussions about the second peak structure. Many suggestions are made to check what is going on: looking at vertex distribution directly rather than the difference; run simulation; try to repeat original vertex by faking the track selection with nHitsTpc+nHitsHft... As for the solution, no conclusion is reached and people agreed to take the discussion offline.
Page 5, why bottom left plot has narrower signal.
As for d0 tree production, Mustafa said it's easy to do twice, without and with primary vertex refit. The computing time and storage is not an issue. So people can begin using the new d0 tree (coming with new pico) and Liang and so on can continue investigating the issue.
3) Update centrality definition for Run14 AuAu200GeV - Guanna
The centrality definition is ready to use.
4) Update on Charm correlation in pp 500 GeV - Long Ma
Simulation show side band is good for pair background discription but wrong sign is not. Page 9 need to be supported by more details, like the reconstructed and tagged correlation plot.
5) update on D+ and D- as well as some studies using a toy mc - Michael, Mustafa
6) the dsmAdc issue - Barbara
7) D0 reconstruction raw signals - Guannan
Page 5, some discussion about the like sign lower than right sign in the lower invariant mass region. It could be other decay channels (3 or more body) signal go into the right sign distribution there. But mixed events seems to reproduce the background better than wrong sign. Need further check and understanding.
There is a comment that having different cuts for different centrality may make the Rcp more dependent on the rightness of embedding.
Embedding is requested for D0.
