STAR HardProbes PWG

[Nihar Sahoo <nihar AT rcf.rhic.bnl.gov>]

Hello Leszek,

After going through Petr's presentation slides, the uncertainty on 
efficiency was calculated based on AuAu data and that has both DCA and 
nhits dependence.
For DCA < 2 cm and nhits >15, that is 5%.
But we need to make sure if this number is true for pp data too.

Some of his presentation are here:
https://drupal.star.bnl.gov/STAR/system/files/TrkEff.pdf
https://drupal.star.bnl.gov/STAR/system/files/2023_PWG.pdf

Let's see if Petr can chime in, otherwise we can contact him offline to 
know the details.

I believe this would be a minor correction to your data and that can be 
fixed at the GPC level.
If you have paper and AN ready, then we can start looking at these.

I hope this helps you.

Thank you
Nihar
