STAR HardProbes PWG

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

Hi Jaro,

The slides look very nice already. Please see my comments below.

Thanks,
Isaac

General:
        There should be a STAR logo in the corner of all slides.
        Looking at the other talk titles in your session, it seems that 
you'll have a somewhat general audience. The slides as currently written 
might be a bit too technical for that audience. You don't have a lot of time 
to radically change the structure, but it would be good to go through it one 
more time with an eye for what a non-RHIC/LHC person would understand or 
might find confusing. As one example, describing elliptic flow and its 
physical implications conceptually in addition to just the equation would be 
good.

7. I agree with your statement that the enhancement can be qualitatively 
described by model calculations including coalescence effects. But it would 
also be good to add a comment (especially since you have space) pointing out 
that none of the models are consistent with the data over the full pT range 
since this may be an area of potential follow-up from modelers.

8. Should mention for clarity that all these models (Ko, Catania, Tsinghua, 
Rapp) incorporate coalescence. Also should be "most models incorporating..." 
Since e.g. the Catania coal. doesn't agree with the data. And is there a 
reason the version of this plot on the left that includes the Cao et al. 
model isn't used?

9.
        Maybe I'm misunderstanding, but is there supposed to be a note for 
the D+- entry in the table as well? It looks like the comment below the table 
is referring to the **, but not sure what the * is for.
        I believe these first two citations are flipped. And why is it 
labeled "D0 2014" rather than just "D0"? Could you also add [#] before each 
citation to match where they're cited in the Hadron column?
        Your first bullet "pT integrated total D0 cross-section per binary 
collision is smaller in Au+Au than p+p" is not possible to discern from the 
table, since the pp D0 X-sec is not shown, right? Could a row be added for pp 
D0 using the value from Fig. 24 of the PRC?

14.
        You say "Low pT < 2 GeV/c: Cold nuclear matter effect" but there is 
additional suppression in AuAu in this kinematic. So I would say "Cold 
nuclear matter effects are non-negligible" or "contribute" so it doesn't 
imply they are the only contribution here.
        "Suppression driven by system energy density"

16. R_CP should be defined.

19 (and 20). Could you indicate more visibly the difference between these two 
plots? I've seen them many times and even for me it took a few seconds to 
figure out that the difference was in the jet radii shown. This comment 
applies more generally as well -- usually things are labeled but the labels 
are a bit small and take a moment to pick out.

21. "lead" and "sub" should be upright in the A_J definition.

22. "Indicates" is a bit strong, since the Hardcore jets should be surface 
biased, so it's not necessarily a claim we can make about all recoiling jets. 
I would say "Consistent with recoil jet losing..." instead.

24.
        "acoplanarity"
        The summary is a bit light on jet takeaways. I know you don't have 
time to talk about everything in the talk, but there is a significant ongoing 
program of pp substructure, pAu jet CNM effects / potential biases, AuAu 
substructure, constituent PID, fragmentation, etc. Since this talk focuses on 
AuAu (although small systems/system size dependence is mentioned), you could 
at least just mention in the first bullet of the summary that jet 
measurements have also made extensive use of these nice 2014 and 2016 
datasets. Or you can at least point to future jet measurements using the 
2023-5 data.
