STAR Correlations and Fluctuations PWG

[Nu Xu <nxu AT lbl.gov>]

Dear Li’Ang,

Thank you for the updated presentation. I have two suggestions:
1) slide 12 - top panels: For pions, I guess that the first bin has large 
systematic uncertainty. Since the bin will not contribute to the fitting 
results, remove the first bin;

2) slide 13 - top left - panel: label pion-pion ==> "pion^_+ - pion^+”.

Hope this is helpful.

Nu

>>  Dear Li’Ang,
>> 
>> Please find below comments to your slides:
>> 
>> Slide 2: 3.5 3.9  -> 3.5, 3.9 
>> 
>> Slide 3: top-left figure: FSI -> FSI +QS (as in case of identical 
>> particles correlations exist due to FSI and quantum statistics as well 
>> (Bose-Einstein in the case of bosons).
>> 
>> Top-centered figure: I don’t get why you highlight just part of the 
>> correlation function, if you want to underline the  presence of the 
>> correlation effect, you should make the rectangle bigger, indicating the 
>> whole correlation effect (q_{inv} unto 0.15 GeV/c, hight up to 2).
>> 
>> Define what you mean by R_G. 
>> 
>> The formula for k* as you present is valid only in case of particles with 
>> identical masses, make it clear please. 
>> 
>> Green frame: clarify what do you mean by probability (probability of what)
>> 
>> Slide 4:
>> Top-left frame: define all symbols mentioned here
>> Top frame: define all symbols here as well,
>> Kaon -> kaon
>> 
>> Slide 6:
>> for 3.5 GeV -> for \sqrt{s_{NN}} = 3.5 GeV
>> 
>> Slide 8:
>> You should not show numerator and denominator of the correlation function 
>> from data if they are not labelled as „STAR preliminary”, remove both 
>> figures.
>> 
>> Slide 9:
>> The same comment applies here, remove figures with data without STAR 
>> preliminary labels. (Both slides: 8 and 9 you can insert instead figures 
>> counting model calculations).
>> 
>> Slide 12: replace new figure, add physics message learned from these 
>> results
>> 
>> Slide 13: replace new figure
>> 
>> Slide 15: Kaon -> kaon (twice).
>> 
>> Kind regards,
