Hello Sooraj,

Sure, I have made the change accordingly.

Here is the updated version: https://drupal.star.bnl.gov/STAR/system/files/CPOD_2024_ver_4.pdf

Hi Rutik,

   Thanks for the update

//These are 2-particle pt correlations between all the particles in the chosen kinematic acceptance, we do not have a qinv. cut for instance to study just the pairs.//

---- 2 particle correlations is too general, we also calculate flow with 2 particle correlations. Better to specify what correlation you measure here. Two particle pT correlations/pT correlation between pairs

Hello Sooraj,

Thank you for your email.

Here are my replies:

L1: their correlations --> pT correlation between particles in an event?

         Yes, we study the 2-particle correlations between all possible pairs event by event.

L6,11: Use either mean p_T or <p_T>

           Done.

L11: 2 particle correlations is very general, specify what correlation is measured. pT correlation between pairs?

        These are 2-particle pt correlations between all the particles in the chosen kinematic acceptance, we do not have a qinv. cut for instance to study just the pairs.

L15: will also be

        Done

L15: 'primordial protons' -- Is this a standard usage/well understood what is meant? 

        So, by changing our acceptance, we can see that the spectator/primordial protons contributions change, the wider the acceptance, the more the spectator contribution,

        the narrower we are around midrapidity, the lesser the spectator contribution.

Hi Rutik and All,

Please remove the sentence starts “We also investigate …” in line 14.
I sign off.
