STAR Flow, Chirality and Vorticity PWG

[LikeLiu <likeliu AT mails.ccnu.edu.cn>]

Dear Subhash,

Thanks a lot for your suggestions!  I have modified the slides accordingly.

https://drupal.star.bnl.gov/STAR/system/files/SQM2022_Like_ver3.pdf

slide#4: "v2 can provide effective degree of freedom" --> Do you mean partonic/hadronic degrees of freedom?
are less affected by  ...
Can you also add some references for small cross-section, earlier freeze-outs etc.

Yes, this sentence was changed to “v2 is sensitive to constituent interactions and degree of freedom”, and some references for small cross-section added.

slide#5: Can you be specific what do you mean by "Better track quality”?

Here I mean iTPC will improve the momentum resolution and extend track detection to low p_T, I will say orally in the talk.

slide#6 and slide#8, 9, 10

The font size inside plot are increased, and "BES-||” label added.

slide#8,Can you point out any improvement in signal/background improvement in BES-II relative to BES-I?

I don’t find the invariant mass dis. for 19.6 GeV, but for 7.7 GeV. Comparison with 7.7 GeV, the signal/background and significance for \Lambda, \Xi, \Omega improved a lot.

https://arxiv.org/pdf/1906.03732.pdf

slide #10"Event-by-event fluctuation dominant" --> Do you mean originated dominant from event-by-event fluctuations?

This sentence was changed to “Event-by-event fluctuation is the dominant source”.

slide#11; Can you add any statement on improvement in precision of NCQ scaling in BES-II relative to BES-I?

In BES-I, we don’t have precision to say the NCQ scaling for anti-particles better than particles, In BES-II 19.6 GeV, NCQ scaling of v2 holds within 10% for anti-particles, 20% for particles, benefit from enhanced statistics. I have add this statement in this slide.

slide#12: "NCQ scaling of v2 observed" --> Seems not true for 0-80%. Suggest to rephrase the sentence.

The sentence was changed to “NCQ scaling holds at 20% level”, the event statistic used and the value of the refmult cut are added on the plot, as Prithwish suggested in the SQM preliminary approval email.

Thanks and best regards,

Li-Ke

Dear Li-Ke,

Nice slides. I have few suggestions for your consideration.

slide#4: "v2 can provide effective degree of freedom" --> Do you mean partonic/hadronic degrees of freedom?
are less affected by  ...
Can you also add some references for small cross-section, earlier freeze-outs etc.

slide#5: Can you be specific what do you mean by "Better track quality"?

slide#6: Can you increase font size inside figures, they are small.

slide#7: Do you want to point out any improvement in PID performance in BES-II compared to BES-I?

slide#8: In general legends are small to read the details, can you enlarge them?
Can you add either 2019 data or BES-II inside these figures?
Can you point out any improvement in signal/background improvement in BES-II relative to BES-I?

slide#9&10: Add either 2019 data or BES-II inside these figures
"Event-by-event fluctuation dominant" --> Do you mean originated dominant from event-by-event fluctuations?

slide#11; Can you add any statement on improvement in precision of NCQ scaling in BES-II relative to BES-I?

slide#12: "NCQ scaling of v2 observed" --> Seems not true for 0-80%. Suggest to rephrase the sentence.

Thanks and regards,
Subhash
