STAR Correlations and Fluctuations PWG

[Kincses Dániel <kincses AT ttk.elte.hu>]

Dear Hanna, Nu,

Thank you for the comments and suggestions, I updated the slides accordingly.
I also compiled a list of answers here:

Tárgy: Re: [Star-cf-l] STAR presentation by Daniel Kincses for CPOD 2024 submitted for review

 

Dear Daniel and All,

I agree with all comments/suggestions offered by Hanna.

In addition, I have the following two suggestions:

1) slide 19 - Summary: (i) “Increasing particle density → rescattering decreases 𝜶?”  the HBT refers to the freeze-out particle correlation. Why does it sensitive to density before freeze-out? It appears that at higher collision energy or more central collisions, the source is further away from Gaussian. I suggest remove the speculation. (ii) Lower - right figure: remake the plot till x-axis to 300 GeV;

2) slide 18 - last bullet: replace "No non-monotonic trend observed yet” by “No non-monotonic trend in alpha observed yet”;

Hope this is helpful.

Nu
