STAR Correlations and Fluctuations PWG

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

Hi Yu,

I went through your slides from the last PWG meeting. I am glad to see the process of d-\La correlations.

I see your results as solid and mature. Good to see that the two analyses agree with each other within systematic uncertainties (slide 16).

For the future, we need to include contributions not only coming from single particles but also to check two-track effects, additionally purity, and resolution smearing. In terms of extracted parameters also, you should check different fitting ranges and what happens if you include/exclude the first one or two points of your correlation function. But having the current state of your analysis, I think we are ready to move forward, and the remaining contributions you can include for the final results. 

Moreover, we need to work more on comparing data with model predictions, especially ensuring that we apply the same approaches to extract interaction parameters from data and when comparing them with the model (UrQMD). The formalism used to calculate the correlation function from the model should be the same as that used to extract parameters (I guess LL formalism). But at this moment, I sign off figures from slide 22.

Thanks,

Hanna

Dear Toshihiro, Hanna, and All,

Can you please also add us to the agenda?  We want present some updates on the d-Lambda correlation measurement at 3 GeV.

Thank you.

Best,

Yu

Dear Toshihiro and Hanna,

On behalf of the PAs,  I would like to request the preliminary for pion femtoscopy at 3.0, 3.2, 3.5, and 3.9 GeV.

Please kindly add me to the agenda. Thank you!

Kind regards,

Vinh
