STAR HardProbes PWG

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

Hello Youqi,

Sorry, I could not concentrate on your presentation yesterday, for me it 
was too late.

I went through your presentation today.
Could you answer the following questions from your your slide?

SLide6-7:
you try to correct  reco-pT to true pT correction based on JES.
On slide-7 lower right plot, "data after mistagged subtraction and pT 
correction" are plotted on the same binning "data after mistagged 
subtraction". I was expecting it will only change your x-axis for 
pT-correction. What am I missing here?

And also it is not clear how do you perform this correction. Could you 
give a try to explain me?


General comment:
Not sure, if you are correcting your rc vs. jet pT results using 
unfolding by creating 2D response matrix using.
For example, Pythia and Pythia+Geant simulation.
Or have you  tried that way?

Cheers
Nihar
