STAR HardProbes PWG

[Andrew Tamis <andrew.tamis AT yale.edu>]

Hi Isaac,

Thank you very much for the comments, i have addressed them and am attaching a new version.  I was unable to update the page, and get an error "path is already in use" potentially because of the duplicate post.  Let me know if i should recreate the post with a different title.

I implemented them all as suggested, but for the comment on slide 2, I was originally planning to verbally mention my correction method before showing results, as these are the previous preliminaries corrected using a method that I am no longer using.  So i was planning to explain verbally that situation, and briefly how they were corrected, without making it a slide, in order to save space for my explanation of my new unfolding method later.

Also I noticed that i had mixed up like and opposite in the label on slide 8.

Best,
Andrew

Best,
Andrew

Hi Andrew,

This will be a fun talk. I have some comments below — nothing major, as it’s already looking good.

Thanks,
Isaac

2. Why specify "jet pT" here? Why not just generically must correct for detector effects? Although here I would probably remove the bullet altogether and just mention more about the detector, e.g. that the BEMC is also used for our trigger for these measurements. You can still mention as you transition between this and the next slide what corrections you need to do to get the results we see. In fact, you might even consider a slide on the details of the analysis, because it's pretty abrupt to have: title slide -> STAR detector -> corrected result in three slides. And it's all the hard work that you did, which you should get to mention!
        In the first bullet it would be good to specify what resolution you mean (momentum, angular,...).
        In the second bullet, I would focus in the text on what the BEMC itself measures, rather than go one step further to mention jets. Of course you can still verbally say that having the BEMC over the full azimuthal coverage allows us to reconstruct charged+neutral jets.

5. "roughly consistent" -> "comparable"

7. I would reframe this a bit as less about the models and more about the physical mechanisms in nature. So instead of "Different hadronization models", how about "Hadronization may introduce..." Then we can move on to test whether one of these models is closer to how QCD really works.

11. Now that I'm comparing the preliminary plot to the plot from Kyle and Ian on s. 8, I'm noticing that the behavior of Pythia and Herwig is flipped (instead of the like (opposite) distribution shifting to lower (higher) angle, it's the reverse). Do you understand why? Is it something to do with the kinematic selection difference, or the initiator flavor difference?

12. I think this last bullet should be tuned up a little bit. We know that Pythia and Herwig do a pretty good job describing hadronic data for other observables at RHIC energies, so I think you'd need to be a bit more specific about what may be failing here.

14.
        "compliment" -> "complement"
        In the conclusions it would also be good to mention something about the physics that we observed with the measurements, maybe in the third bullet (your choice).
