Dear Nu,

Thanks for you suggestions. I have implemented them, please found the slides in below link:

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,
>> Hanna
