Hi Neil,

After our offline discussions today about the correlated/uncorrelated systematic uncertainties, I am happy with your preliminary request slides.

Thanks,

Isaac

Hi Neil,

Thanks a lot for the prompt action and updated version. It looks good to me.

Cheers,

Hi Yi, thank you for your comments. I have implemented your suggestions here. https://drupal.star.bnl.gov/STAR/system/files/PreliminaryRequest_QM_Aug20_2023_v4.pdf

General comment: For the plots without the LIDO comparisons, I have labeled them 'Without Theory'. I just kept them on the slide in case we want to show versions without the theory curve at some point.

Some comments below:

p5: could you please make a list of the sources of the systematics? 

A: I have listed all of them on p4.

Cheers,

Hi Neil,

Thanks a lot for the preliminary request. They look good. I have some suggestions for your consideration. 

 - p5: could you please make a list of the sources of the systematics?  

 - p.8: label on Y-axis: I would remove "Central", "MidCentral", and "Peripheral", only keep "0-10%", "10-40%", and "40-80%".   

 - p.9, p10: These plots are the same as p6 and p8, except adding LIDO? If so, I don't think you need to have separate requests since we are proofing the data points, but it is okay to keep them in the slides.  

 - p.13: similar comment for p.8

 - p.14, p15: similar comment for p9 and p10

 - p17: similar comment for p8

 - p18, p19: similar comment for p9, p10

Cheers,

Yi

Hi Yi, thank you for letting me know. I don't understand what happened, but I can't access the drupal link either. I have reuploaded all the plots and the preliminary files here: https://drupal.star.bnl.gov/STAR/blog/droy1/Preliminary-Request-D0-Meson-Tagged-Jets-AuAu-200-GeV-0

The preliminary request file is this: https://drupal.star.bnl.gov/STAR/system/files/PreliminaryRequest_QM_Aug20_2023_v3_0.pdf

The QM poster is this: https://drupal.star.bnl.gov/STAR/system/files/QM2023_Poster_Diptanil_36x48_v2.pdf

Thank you.

Hi everyone, thank you for your comments yesterday on the preliminary request. I have implemented all of them, and added key physics messages on the slides. You can find the updated version here. https://drupal.star.bnl.gov/STAR/system/files/PreliminaryRequest_QM_Aug20_2023_v3.pdf

Kindly let me know if you have any further questions/comments.

Hi Nihar, thank you for your comments. I have implemented most of your comments in v2 of the preliminary request. Please find v2 here. https://drupal.star.bnl.gov/STAR/system/files/PreliminaryRequest_QM_Aug20_2023_v2.pdf

Some comments:

Please include physics message that you conclude or observe on each
slides where is needed.

I will, after the discussion in PWG tomorrow.

Why statistical uncertainties increases at smaller (0.-0.05) relative to
larger ΔR (0.1-0.2) ?
This was not seen in your previous STAR preliminary results for 5-10 GeV
D^0 case.

So, the statistical unc. is dependent on a lot of factors: Actual counts, sWeights, unfolding output. So, I can't point to one of them specifically, but I suspect it's due to unfolding and sWeights.

What I see is this:

The ratio errors depend on Central and Peripheral errors.

For Bin 1:

Central Error % = 4.73

Peripheral Error % = 7.47

For Bin 2:

Central Error % = 3.60

Peripheral Error % = 5.83

I checked that the errors are being propagated to the ratio properly.

Hello Diptanil,

Thank you for posting your preliminary request slides.

A few suggestion on your slides and plots.

1) Please include physics message that you conclude or observe on each
slides where is needed.

2) Slide10:
Left plot, have you used symmetric systematic uncertainties? If yes, the
z bin=0.2-0.3  looks a bit strange (like asymmetric). Please check it.

3) Slide6:
Y-axis:  d^{2}N -> d^{2}N_jet
pT,jet -> make the same as X-axis label
eta -> eta_jet
[and same for other plots]

4) SLide7 and 10:
Y-axis Lower limit: Make it upto Zero.  (Or make it Semi-log in Y-axis)

5) Where do you get T_AA values for these centralities (like 40-80%)?

6) Can you show T_AA scaled D^0 jet pT spectra and Z spectra for 10-40%
and 40-80% centralities? Just to see one step back to get nuclear
modification factor.
And please plot on figures in Slide#6 and #9 for a comparison (for our
internal).

7)Slide13:
Why statistical uncertainties increases at smaller (0.-0.05) relative to
larger ΔR (0.1-0.2) ?
This was not seen in your previous STAR preliminary results for 5-10 GeV
D^0 case.


Let's discuss also at Tuesday meeting.

Cheers
Nihar
