STAR Correlations and Fluctuations PWG

[Wielanek Daniel <Daniel.Wielanek AT pw.edu.pl>]

Dear Privanka,

Thank you for the information. I would like to present more of our (STAR) results, however, due to space constraints, I'm afraid that I cannot add more slides. Thank you for your understanding.

Pozdrawiam/Best regards,

Daniel Wielanek

Dear Daniel,

I was going through your nice presentation. Though I can't access it now. If possible, you may consider my results from our latest presentation slides of ICHEP. Slide no. 12, 13, 14 contains the results which you may keep on a single slide. Here is the reference slides.

Subject: [[Star-cf-l] ] Odp.: Odp.: STAR presentation by Daniel Wielanek for NTHEP-2024 submitted for review

 

Dear Hanna, Mate,

I uploaded never version.

I modified part with vHLLE+UrQMD model. The point is that model have some free parameters, and those parameters were tuned only for crossover EoS. It is therefore possible that another parametrization give oposite results (1PT will better describe the data).

That I want to avoid a statement that this model favors crossover EoS.

Pozdrawiam/Best regards,

Daniel Wielanek

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
