STAR HardProbes PWG

["Mooney, Isaac" <isaac.mooney AT yale.edu>]

Hi Priyanka,

I have no additional comments on your nice slides, pending the possible addition on slide 19. One comment to Nihar: on s. 16, I would call that consistency between the model (pink) and data across the entire domain, within statistical and systematic uncertainty of the data and theoretical uncertainty on the model. By eye it looks like < 1 sigma deviation of the central value from the model value in the lowest k* bin. Maybe the deviation when combining both of the lowest two bins gets above 1*sigma, but since the lowest bin is where the qualitative behavior of the model is changing, it seems that would be the region where we want to know the consistency or lack thereof. Priyanka could comment if she has the exact numbers for deviations of the data and model as a whole with all bins, and/or just with the lowest two where there may be some slight tension, and/or the value for the very lowest bin. But to me it seems that what she is trying to say is: "yes the data are flat, but within uncertainty, do they also support a physical picture which has some effect at low k*? Yes." And I think that’s a valid interpretation, given the plot.

Thanks,

Isaac

Hello Priyanka,

Nice Slides. Additional to Nihar's comments, please find my comments below:
Slide 4, Please give a reference to this page.
Slide 6, it is sqrt(pi) rather than sort(2) in equation (1).
Slide 12, If your analysis just used part of the data, then you should mention it.
Slide 13, Background is not shown in the plot (either SE-LS or MX-UL)
Slide 16,17 and 18, It will be good to point out how you deal with different spin states and its relative fraction.

Hello Priyanka,
Please find my comments on your nice slides.
_Slide2: Please provide reference of this cartoon [ALICE experiment’s probably]
_Slide16, “STAR data shows no significant correlations, but the data
is also consistent with theoretical model
predictions with emission source size of 5 fm or larger” -> It is not
correct. It is not consistent at low k*. Please correct it.
_Similarly in Slide 17, It is consistent within uncertainty at low k*.
Please clearly mention it.
_Slid18:  “We do not observe significant correlations between D0-p
pairs” -> on “Significant correlation”, who do you know this is not
significant? I think at low k* we see some correlation., but you have
larger bin size so last point only shows this correlation. Is not it?
_Slide19:  Either you drop this slide with “place holder” or you
finalise this slide  before we sign off.
Best
Nihar

Dear all,
Please have a look at the submitted slides for the upcoming Zimanyi
school. Slides are almost similar as WPCF with a place holder in slide
no. 19, which should be finalized soon.
Regards,
Priyanka
