STAR Correlations and Fluctuations PWG

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

Dear Grigory,

Please find below my comments to your slides:

Slide 2: Critical Point is still hypothetical,. 

We know from STAR that a low energies (~ \sqrt{sNN} = 3 GeV) the Critical Point is not expected.

Avoid term „low energies”, substitute by something more relevant and do not write „Presence of CP” as you don’t know it.

While you mention we need higher statistics, specify what do you mean by „higher”.

When you write „Increased detector acceptance”, add what you gain (in terms of statistics)

Mention which   \miu_B we can access with 3 programs: BES-I-, BES-II and FXT (FXT is not mentioned at all at the collected statistics plot while you show it at the QCD phase diagram)

Slide 5: It is not necessary to mention 200 GeV (not a part of BES program)

Do you intend to concentrate on BES-II + FXT only? As most STAR results come from BES-I, it would be good to mention statistics collected from BES-I too (especially as you mention later results from BES-I)

Slide 6: Describe what can be learned from both plots including R_{out} and R_{side}, information provided on then slide is very modest

Slide 7: Write correct definition of q_{inv}, define S(r, k), \Psi_{1,2}(r,k)), add vectors signs under vector quantities

Add vectors under momenta: p_{1z}, p_{2z}

Slide 8: FSI was already defined at slide 7, write just FSI, expand  what do you mean by transport properties and symmetries..

About plots: describe reaction of the collision, energy, types of articles, add legends

Slide 9: as STAR published very nice results for 4.5 GeV, please add them to the left plot. 

Middle plot: consider showing plot from 4.5 GeV paper, it better explains collision energy dependence of R_{out}/R_{side} and R^2_{out}-R^2_{side}

Hybrid models: explain what do you mean.

Explain what do you expect from heavier particles (and what kind of particles do you mean)

Slide 10: the title relates to kaons while you show pions too, rename the slide

Top left: add a legend to blue line too,  specify which pions and kaons you included

Bottom left plot: specify which pions and kaons you included

Mark/explain where do you see that FSI is needed to describe data (kaons?)

About kaon femtoscopy: Diana has beautiful results for K^0_S-K^{ch} too, showing all combination of neutral and charged kaons together makes sense as they complement each other and help to choose the proper parametrization of the strong FSI. Refer of Diana’s SQM or HYPERON  presentation and pick her results

Saying „excited physics program” what do you mean? BES?

Slide 11: other -> others

Slide 13: specify what kind of expectation do you mean

Specify: specify: excellent performance of .. what?

Remember that BES-II ends at 19.6 GeV, BES ends at 62.4 GeV (you even show it at the slide 2)

Specify what kind of precision analysis are ongoing..

Thanks,

Hanna
