STAR HardProbes PWG

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

Hi Yuan,

I’m happy with the updated materials and the paper is looking even better. 
Thank you for carefully considering and implementing my suggestions. From my 
side, it’s okay to move ahead to GPC formation.

Best,
Isaac

Hello Yuan,

First of all, sorry for this delay.

I have gone through your paper draft. It is in good shape.
A minor comments can be found below. And I sign off.

We will be working on to request for GPC formation asap and you will be
informed.

1.  "….less gluon formation time and suppressed gluon radiation with a
small angle (dead-cone effect) result in less radiation energy loss.."
-> This sentence needs some work, For instance "less", "small angle" not
mentioned with respect to what. ; "radiation energy loss" -> radiative
energy loss
2. …nuclear size R_A dependence are quadratic … -> I would suggest to
use different notation for nuclear size "R_A" as we use "R_AA", better
to avoid
3. …statistical isobar data based on the RHIC experiment provides… ->
…statistical isobar data provides [ based on…, sounds awkward]
4. due to its large mass, mc,b >> ΛQCD,… -> is not that also mass
relative to "temp of the medium"?
5. To improve the significance of the D0 signal, a blind analysis based
on a large data sample is performed.  -> Is that true? Not sure blind
analysis was conducted for this analysis.
6. MB data samples but also can … -> ..MB data samples but also it can…
7.  Fig.1: Need to mention centrality or total MB event inside Fig

9. All variables' notation that has a "value" should be "italic". Non

10. "…derived from various charm-hadron decay channels containing…" ->
Please provide 1-2 channels example
11. Eq.9, Make \it{N}_bin

"generated from the hard scattering" [generally all hard scatterings are
by initial partons]


Thank you

Dear conveners，

The materials of D0 R_AA analysis in isobar collision are ready. If
it's ok, we would like to push them to PWG review.

Dear conveners and all,

As we had tried to fit the pi/kaon/p spectra in isobar by Blast-Wave
function, we have implemented PWGC preview comments.

please find it at:

If it's ok, we would like to put forward to PWG review.

Thanks and best regards,
Yuan

Presentation:

The PWGC panel previewed a paper proposal from HP PWG. The panel
found
that the analysis is mature and results are important and
interesting,
and the paper should move forward. The journal choice was also
found
to be appropriate. The following points were discussed.

Q: R_AA comparison vs centrality or N_part, do we plan to show
both,
what is the conclusion ?
A: We don’t have enough precision to say we are in agreement
with
Au+Au at the same N_part or centrality interval.

Q: Slide 17: There is large centrality dependence of the extracted
T
and beta parameters for D0 and they are very similar for Au+Au and
isobars at the same centrality while one would expect the same
temperature for the same N_part.
A: The uncertainties are too large to draw conclusions.

Q: D0 R_AA comparison to theory - which model is it ?
A: This is a new calculation for isobars using the framework from
TAMU, but it’s not published.

Q: Why are there so high systematic uncertainties at low pT in Raa
and
why is it asymmetric ?
A: Because there are no data points there for p+p, it comes from
extrapolation from the Levi function and uncertainties on this are
from fits of other functions.

Q: Slide 16: light particles are from Au+Au ? Can we add isobar
results here ?
A: This is a good suggestion, but the pi/K/p results are not
published
yet.

Q: Slide 12: What are the three types of errors for Au+Au ?
A: The shaded bands are from N_bin uncertainties

Q: Slide 12: Why does p+p have such large statistical errors ?
A: There is extrapolation involved.

Q: Slide 17: Have you tried the same Blast-Wave fitting for p+p ?
Would be interesting to compare to HI results.
A: We can try to perform the fit.

Q: Can we have a comparison of R_AA to the theory for Au+Au ?
A: Yes, it is published, we can add to the plot.
