STAR HardProbes PWG

["Ma, Rongrong" <marr AT bnl.gov>]

Hello Priyanka

I am terribly sorry for overlooking your nice results. I have included one slide (s14) on this now: https://drupal.star.bnl.gov/STAR/system/files/RMa_CFNS_npQCD_v3.pdf. 

In trying to understand the theoretical calculations shown in the figure, I quickly read through the relevant part in https://doi.org/10.1103/PhysRevD.108.014020. However, I still could not fully understand the behavior due to my lack of knowledge, and hope that you could help me. 

My main question is why the correlation function is suppressed at low k*, and why the suppression gets stronger with smaller source size. Also there is a small bump around 80-90 MeV for the distribution of R = 2 fm. Is this due to D+K0 channel as mentioned in the paper? If so, why would it create a bump in D0K correlation function?

Thanks. 

Best

Rongrong

Hello Rongrong,

I have a quick comment regarding your well-prepared slides. I was wondering maybe you have missed our preliminary plot ( C(k*) for D0-K) to include within your slides. 

Regards,

Priyanka
