STAR Correlations and Fluctuations PWG

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

Hello Mike,

Thank you very much for your update.

I agree that adding another figure that you mentioned will improve the paper and emphasize pion femtoscopy's importance for a considered range of energy.

Thanks a lot,

Hanna

Hello CF groupies,

 

As you know, STAR has a paper on flow and HBT in Au+Au at 4.5 GeV, fixed-target configuration, which has submitted to Phys. Rev. C.  You have seen on the starpapers list the referee report, which is relatively straightforward to respond to.  As the PAs put together our response, we decided to add another figure, to emphasize the importance of pion HBT radii at this crucial energy.

 

Even though there is no data on this plot that isn’t in the other figures in the paper, I thought you would like to see it, as it gives a clear picture of the famous “R_out over R_side” issue.  Please look at figure 20 in this pdf file:

https://www.star.bnl.gov/protected/bulkcorr/ywu27/fxtPaperWeb/Fixed-Target_Paper_Proposal_files/GPC273_Draft_2point4point1_FXT.pdf

It is discussed in Section VI.B.3

 

It’s really nice to have this new low energy point, together with the HADES point from GSI.  However, note that we have already published this graph (minus those two points) in our long BES paper, Phys. Rev. C 92(2015) 14904.  You can see the figure (figure 7) here:

Best regards,

Mike
