STAR Flow, Chirality and Vorticity PWG

["Huan Zhong Huang" <huang AT physics.ucla.edu>]

Hi CW,

  On slide 7 what do you refer to when you discuss autocorrelation? What exactly is the autocorrelation that you are concerned with here?

  On slide 9, you showed a relation between v2 and q2. We saw the similar relationship in Zhiwan/Gang’s analysis. For centrality bin of 20-50%, the averaged v2 is within a small range as shown in your figure. In our attempt to do Event-Shape Selection, we try to select a small class of events fluctuated towards more spherical shape (small q2).  What we find is that the fluctuations of q2 in different eta windows or different subset of particles are not correlated at all. Because of this semi-independent fluctuations, one cannot use the so-defined q2 as a dial to select spherical events for particles of interest. Essentially, one tries to use an ineffective dial to select the event shape.

  Why are these fluctuations in q2 from different eta windows so independent? There may be deep dynamical reasons that we do not know yet.

  It may be useful for STAR to evaluate the different Event-Shape Selection approaches. We should make sure that different approaches should be clearly explained if seemingly different results will be presented.  

  Thanks. Regards,

  Huan

Hello Conveners,

 

I have updated my slides to include a copy of the 

\xi vs. N*Dgamma plot which includes the separate DeltaS, single normalization data series (pink points). 

 

Please see Slide 12.

Thanks!

Dear conveners,
 I would like to give a presentation on preliminary request of Event Shape Selection study on CME in Au+Au at 27 and 19.6 GeV. Please kindly add me to the agenda. Thank you.
Best,
Zhiwan
