Hi Qian,

thanks for the update. The slides are very nice, please find my comments below.

Cheers,

Barbara

s3 - I would also mention CNM effects

s4 -  How it affect ->  How is it affected

s5 - w be established -> evolves (?)

s6 - v2 -> v_2

s8 - make the left plot larger 

s9- dependence were shown -> dependence is observed

s11 - you can emphasise here precision of the isobar measurement

s13 - it would be good to have better quality plots here. Maybe Yu-Ming can prepare example procedure figures with better graphics. Also, are these efficiency weighed, is there some physics one can extract ?

s14 - I think it makes more sense to compare 0-80% isobar to 0-80% Au+Au - so to have the Au+Au results on the left plot. But let's also see what others think and we can then decide on the final version of these plots.

Also, for the 20-60% range please keep in mind that Yu-Ming might have his HT results early next week - in this case please update the plot.

s15 - since we have higher pT results it would be nice to have here also the integrated v2 for higher pT > 4 GeV/c from the HT.

s15 - it's not so obvious to me how much better precision we have in isobar compared to Au+Au. Is it possible to combine Au+Au for pT < 4 GeV/c ? Also, I think it would be better not to combine stat. and sys. uncertainties for Au+Au results (also for the other comparison), it might show better statistical differences between the two results. 

s15 - for low pT, i.e. ~< 1 GeV/c, we expect 0 v2 because of the mass effect. If it's fast, can you calculate integrated v2 for pT > 1 GeV/c ?

Hello All

  As we discussed in yesterday's HP meeting. I have updated the slides to
a new version.
