STAR Flow, Chirality and Vorticity PWG

[Shengli Huang <shengli.huang AT stonybrook.edu>]

Dear Fuqing,

    If full event nonflow is a factor two of subevent with deta>0.7 as paper state, then the difference between full event and subevent will cover the nonflow of subevent, right? 

Thanks!

Hi Shengli,

Yes, this is the right paper. Fig.5 left most central point (black/open circle)^2~10% (note the open is scaled down by x2). This is for Deta>0.7. From Fig.4 left full event is about x2 of that at Deta>0.7. So that’s the 20% I was saying. The uncertainties are relatively large. 

Best regards,

Fuqiang

Dear Fuqiang,

     I just read the paper about nonflow in PWG discussion today:

https://arxiv.org/pdf/1409.2043.pdf. 

First I hope I find the correct one and understand it accurately. 

According to this paper, it is stated that the nonflow is only 5% in 20-30% AuAu with deta>0.7, which differs significantly to 20% in central AuAu as you said. Can you tell us more details to understand it?

Thanks!

Shengli
