STAR Correlations and Fluctuations PWG

[Mate Csanad <csanad AT bnl.gov>]

Dear Hanna,

For the slide Daniel kindly included (S26), let me send some thoughts.

- I guess Daniel meant by "nontrivial" nonmonotonic, as the (naive) expectation 
would be a nonmonotonic change in alpha(sqrt(sNN)), more specifically, a 
minimum. I would actually write: "Minimum predicted in alpha(sqrt(sNN)), not 
visible in the data". A reference could be:
https://arxiv.org/abs/nucl-th/0512060

- I think what can be stated (verbally) very quickly and clearly is the 
following:
 * With collision energy, not just the source size (R) but also the shape may 
change, and this latter is characterized by alpha
 * According to the measurements, calculations based on a Lévy-shaped source 
describe the data well, and alpha can be extracted for each energy
 * It was predicted that there would be a strong decrease of alpha near the 
critical point, not visible in the data so far
 [* While alpha changes monotonically and smoothly with sqrt(sNN), the size and 
shape are entangled if alpha=2 is assumed, hence this observed alpha(sqrt(sNN)) 
trend indicates that the source size with Lévy assumption has a different trend 
with collision energy as compared to the source size with Gaussian assumption] 
This last point may or may not be included, depending on time. Otherwise these 
things can be told quickly, clearly and efficiently, I think.

Best regards,
Mate
