Dear Sooraj,

Thank you for your comments. I have implemented them and the new version has been uploaded to the following link: https://drupal.star.bnl.gov/STAR/presentations/SQM-2024/Measurements-Kaon-Femtoscopy-AuAu-Collisions-sNN-30-45-GeV-STAR-Experiment

Please kindly let me know if there's further comments or suggestions.

Thanks and regards,

Bijun

Hi Bijun,

   Thanks for these well prepared slides. I have only a few comments. Please find below

S4: first bullet: including only

S4: to includes --> to include

S10: CARB --> CRAB

S10: with experimental data

S10: parameters for Ks0

S14: R_G of kaons don't follow

S15: R_G of kaons

Best,

Sooraj

Dear Bijun,

Thank you for posting your slides on time.

I have following comments regarding your nice slides (I comment on version 4 of your presentations).

Slide 2:

m_T- scaling. -> m_T - scaling (add spaces)

Slide 3:

Please define k* and r*.

Top-right figure shows the correlation function as a function of q_{inv}, since you use k* on your slide, I suggest to change q_{inv} to k*.

However, you also need to define q_{inv} as your results are shown as a function of q_{inv}, so you need to mention PRF and LCMS reference frames (define them) and show the relation that if m_1 = m_2 then q_{inv} = 2k*.

Slide 5:

Define t, L from  m^2 formula.

Slide 10:

Please add more details about UrQMD and CRAB, mention model configurations to avoid confusion  

Slide 11:

Mention how you subtracted pure-QS correlation functions (discuss the FSI parts)

Slide 12:

Specify what do you mean by Model (version, configuration, etc..)

Kaon -> kaon (three time, 2nd and 3rd bullets)

Slide 13:

Kaon -> kaon

Slide 14:

Kaons-> kaons (twice)

Slide 15:

Kaon -> kaon (5 times)

m_T-scaling -> m_T - scaling (add spaces).

Thanks,

Hanna

Dear Nu,

Thank you for your feedback. I have made the necessary updates. You can find the new version at the following link: https://drupal.star.bnl.gov/STAR/system/files/SQM_Kaon_HBT_v4.pdf

Best regards,

Bijun

Dear Bijun,

Thank you for the updated draft. I sign off.
There is one small correction in slide 15 - "2) R_G of Kaons don’t follow 𝐦𝐓-scaling of pions’, “ ==> “2) R_G of Main does not follow mT-scaling of pion’s”

Best regards,
Nu

So one would expect the lambda parameters become larger at higher pt region. This is what we know in literatures.

Regarding the second point, I have cross-checked with YouQuan's 1D results and observed that the lambda value does increases with lower kT, which is contrary to the findings of the 3D analysis in the same energy range. The published results from HADES also exhibit a similar trend (refer to the figure below).
