STAR Correlations and Fluctuations PWG

[Hanna Paulina Zbroszczyk <hanna.zbroszczyk AT pw.edu.pl>]

Dear Yevheniia,

Thank you very much for your presentation yesterday. I could only listen to it, but I had seen your slides before the meeting.

Thanks for adding an entry to the preliminary page.

Regarding your presentation, after yesterday’s discussion and comments from Nu that you implemented, I sign off.

Enjoy the conference,

Hanna

Dear Hanna and Nu,

I updated my talk according to today's meeting discussion: https://drupal.star.bnl.gov/STAR/system/files/wwndKhyzhniak_1.pdf

I also added link to my preliminary plots to the page with all reliminaries: https://drupal.star.bnl.gov/STAR/blog/gos/correlations-and-fluctuations-preliminary-plots

Thank you,

Yevheniia

Dear Yevheniia,

Thank you for posting your talk in advance.

I can’t find your results in our preliminary page:

https://drupal.star.bnl.gov/STAR/blog/gos/correlations-and-fluctuations-preliminary-plots

We should discuss during next CF PWG preliminary requests to results you intend to show during WWND.

Thanks,

Hanna

Dear Nu,

I've updated my slides: https://drupal.star.bnl.gov/STAR/system/files/wwndKhyzhniak.pdf

>lide 42 - Summary - 4th and last bullet: (i) The ‘good agreement’ between data and the UrQMD calculation is reached only for '7.7 Au+Au collisions, 30-50% centrality, from the SL correlation'. It is not the case, for example see slide 41, for 10-30% collision centrality. Please add these conditions to the bullet;

I tried to clarify what I meant in my updated summary slide. Please take a look.

>Why it is important to observe the consistence between the HBT result from the pair measurement and “the tilt from the freeze-out distribution” from single particles, at k_T = 0?

I'm looking for the correspondence between HBT results and freeze-out (FO) distribution of pions, but I'm not claiming that those have to be the same. This is more like a test. I'm extrapolating my HBT tilt to zero kT in order to get the biggest possible homogeneity region and trying to see if the HBT tilt agrees with the same from FO dist.

>slide 42 - 2nd bullet - up-right figure: Where did you find the data points from low collision energies? In the listed reference, I could not see the experimental data points.

You're right, thanks! I mixed it up with another PLB paper from 2000. I've put the right one now. Please take a look.

Thank you,

Yevheniia

Dear Yevheniia and All,

Here are my suggestions/questions about the draft of your WWND2024 talk:

1) slide 42 - Summary - 4th and last bullet: (i) The ‘good agreement’ between data and the UrQMD calculation is reached only for '7.7 Au+Au collisions, 30-50% centrality, from the SL correlation'. It is not the case, for example see slide 41, for 10-30% collision centrality. Please add these conditions to the bullet; (ii) Why it is important to observe the consistence between the HBT result from the pair measurement and “the tilt from the freeze-out distribution” from single particles, at k_T = 0?

2) slide 42 - 2nd bullet - up-right figure: Where did you find the data points from low collision energies? In the listed reference, I could not see the experimental data points.

Thank you,
Nu
