STAR Correlations and Fluctuations PWG

[Q Z <qinz18 AT outlook.com>]

Dear Mate,

Thanks for your very nice comments, we updated the slide at:

https://drupal.star.bnl.gov/STAR/node/59019

For the plots on slide 4, they are not the physics plots but the technical plots, so they don’t need STAR preliminary, we have discussed those plots in the PWG meeting. Thanks for your suggestion, we have added the 0-60% Au+Au@3GeV in the plot. 

On slide 2, we change to use C(p_a, p_b) on the first equation(can be any frame, usually lab frame), thanks for clarifying.  

Thanks and Best Regards,

Zhi

Dear Zhi,

Thanks for the new version and for carefully responding to all points raised.

There are two minor format issues:

- for slides 2-5, please add STAR logo to the header (maybe also QM logo, in the
opposite upper corners)

- still for slides 2-5, please also add your name (without institute) in the footer

One more issue is with the plots on slide 4. As you say that this is really
data, especially the right hand side plot, then this should be made preliminary,
by adding:
* collision system, collision energy (and maybe centrality)
* STAR preliminary
or there is a specific reason not to do so? Maybe this issue was discussed in
the CF PWG? If so, then of course I am okay with it. But normally, I would think
that all physics data plots should have these labels.

Also, on slide 2, I think every momentum could be in the PRF (anyway, left side
of the first equation is already in PRF), and then there is no need for a STAR;
it is not clear in what frame p_a and p_b (without '*') are - probably lab
frame, but of course can be any frame. Or the first equation could start as
C(p_a,p_b). But this is really minor, I am okay leaving the entire box as it is.

Thanks,
Mate

>> Hi Zhi and Yingjie,
>>
>>      Nice poster, please find my minor comments below :
>>      1. Slide 1, Please put ONLY ONE name there for the STAR collaboration.
>>      2. Slide 2, In the 3rd bullet of the motivation : "An attractive
>> p-Xi interaction is observed in p-Pb and pp collisions at ALICE "
>>         Please change to "An attractive p-Xi interaction has been
>> observed in Au+Au 200 GeV at STAR, p-Pb and pp collisions at ALICE "
>>         Since previously, STAR has reported p-Xi results at 200 GeV and
>> claim the observation of the attractive interaction in p and Xi.
>>
>>      With this implemented, I sign off.

>> Thank you,
