STAR Correlations and Fluctuations PWG

["樊碧君" <bjfan AT mails.ccnu.edu.cn>]

Dear Nu and all,

Thank you for your comment. I Have remove the pion mT dependence of lambda parameter in slide 12, and the new version can be found in the following link: https://drupal.star.bnl.gov/STAR/system/files/SQM_Kaon_HBT_v4_0.pdf

Thanks and regards,

Bijun

Dear Bijun, Youquan and All,

Due to combined effects of (i) momentum resolution coupled with centrality; (ii) resonance decay contributions; (iii) multi-particle coherent effects, and all of these effects become stronger at the low pt region. So one would expect the lambda parameters become larger at higher pt region. This is what we know in literatures.

Before we understand the mt dependence, I again suggest we remove the pion lambda mt dependence plot in this presentation.

For Youquan, do we have the corresponding analysis from the UrQMD simulations?
I mean the mt dependence of pion mt dependence from 1D and 3D analysis.

Many thanks,

Nu

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).
