STAR HardProbes PWG

[Tristan Protzman <tlp220 AT lehigh.edu>]

Hi Nihar,

I have updated the slides with your comments: Preliminary Figure Request: Azimuthal Anisotropy of Jets in √(s_NN )=200 GeV Ru+Ru and Zr+Zr Collisions (bnl.gov)

1) If I look at your Slide#14 jet v2 plot, the systematic uncertainty
bands for 1st and 3rd bins are relatively tiny compared to other bins. 
Generally systematic uncertainty should show a continuous variation
throughout the bins. Hence I suggest to use the 2nd bin's sys
uncertainty for 1st bin and average value of 2nd and 4th's sys
uncertainty for 3rd bins. For future we can discuss and work on it.
Same for the plot in slide#15.

I have made this change.

2) SLide#14 and 15 płot, Please include inside each figure "No jet
pT-correction applied".

Sure, I had removed it since I thought it was redundant with the labeling of the x-axis as p_{T, jet}^{reco, ch} but I have no issue including this label.

THis is a very nice study on two extreme cases for jet v2 values.
But there is one point I want to make here (that I forgot to discuss
yesterday's meeting) that we need to check this study when you increase
for jet R > 0.2; probably this we can discuss after HQ.

Certainly, we wanted to start with R=0.2 jets since we expected it to be the simplest to understand the background and such.  As we vary the parameter space I plan to continue to come back to this toy model and verify that we still understand the behavior.  

Let us know when you finish this and update all your sys. uncertainties.

Certainly, my jobs are about 15% complete. 

Cheers,

Tristan

Hi Tristan,

Great, it looks good.

Two suggestions on your results.

1) If I look at your Slide#14 jet v2 plot, the systematic uncertainty
bands for 1st and 3rd bins are relatively tiny compared to other bins. 
Generally systematic uncertainty should show a continuous variation
throughout the bins. Hence I suggest to use the 2nd bin's sys

2) SLide#14 and 15 płot, Please include inside each figure "No jet

if I find more comment and suggestion, I will let you know.

Remaining comments inline.

this is good.
