STAR Correlations and Fluctuations PWG

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

Hi Li’Ang,

Thank you for your clarification.

I am ok with preliminary labs for the figure from slide 16 (correlation functions).

For better visualization, on slide 17, can you enlarge the horizontal axis? For \lambda we don’t see the total error bars.

With this implemented, I am fine and sign off your results. Please create a new entry and place your preliminary figures there:

Thanks,

Hanna

Hi Hanna,

I prepared short slides to answer your question at here: https://drupal.star.bnl.gov/STAR/system/files/K0sK0sCFPWGResponse.pdf 

Please found my answer in slide: 2 for pair purity correction; slide: 3 for momentum smearing correction.

And the detail plots can be found in rest slides.

 

Cheers,

Li'Ang

Hi Li’Ang,

I went through your slides from the last PWG meeting. I am glad to see the progress of neutral kaon femtoscopy at BES.

Slide 11:

How do you include purity correction in your analyses?

We need to see the pair purity for each collision energy. I assume you consider only one centrality bin 0-60%, right?

Please demonstrate the correlation function for each collision energy before and after purity correction.

I assume that you request preliminary labels for the correlation functions corrected on purity. Am I correct?

Slide 13:

When you calculate the correlation function for smeared momenta (from the model, when you determine the impact of the smeared moments resolution on your measured correlation function), for a given smeared k*, did you calculate the correlation function for the smeared k* or real one? In other words, when you calculate the correlation function for smeared momenta, was the weight calculated for smeared as well, or for real k*?

Thanks,

Hanna

Dear Hanna and Toshihiro,

I 'd like to request the preliminary about K0s-K0s femtoscopy at FXT energies. Please kindly add me to the agenda. Thank you very much!

Cheers,

Li'Ang Zhang

Dear CF Activists,

We will have our weekly CF PWG meeting on Thursday, August 10th, 9:00 AM (BNL time).

If you would like to contribute, please let us know.

Please try to post your slides at your earliest convenient.

We will connect via Zoom. Please find the connection details under the meeting webpage.

Thank you,

Best regards,

Hanna and Toshihiro
