STAR HardProbes PWG

Hi Priyanka,

very nice slides. Please see below my comments.

Please remove the university and faculty logo from slides (except the first one), add STAR logo istead. 

- s5: I would introduce here how the correlation function is measured in an experiment. Otherwise slide 17 is very empty. 

- s5: why is the Coulomb interaction in red ? 

- s6: improve the quality of equations. 

- s9-10: it's nice to show the ALICE results as an example. But I wouldn't go into so much detail of explaining the result. I think one slide and two example plots should be enough.

And I think, but correctly if I'm wrong, that the main idea behind these studies of residual strong interaction between charm and light hadrons is twofold (1) measuring scattering lengths for ND - this is also important input for HI for transport models; (2) search for new molecular states. 

- s11-12: I'm not sure if I follow your motivation for HI. The cited papers are related rather to hadronic physics - search for the exotic hadrons. Could you explain to me how you get statements on slide 12 from this paper and the plots - apologies if I'm missing something. And do you need slide 11 ?

- s15: you don't need the table with all the cut values, you can just write above your bullet points: "Topological selection cuts for D0 reconstruction". 

I would make the decay sketch larger and add what is the proper decay length of D0.

- s16: since you write "Very good signal/background ratio", I would add values of S/B on your invariant mass plots. 

Since you don't show further results, instead of "D0 invariant mass ..." bullet you can write what functions you use for your signal and background fits. 

- s18: we applied following condition -> we applied the following condition for TPC tracks. Also, maybe you have some cartoon showing split tracks. 

- s19: what is missing here is some explanation of what are merged tracks and how they can affect the correlation function. You have detailed explanation of split tracks on the previous track, so this slide 19 is a bit in contrast with slide 18.

- s20: input on of charm quarks -> input on of charm quark interaction

One will need model calcinations that include details of charm interactions with the QGP -> Model calculations needed 

Cheers,

Barbara

Hi Priyanka,

I have a small comment on your interesting slides that you’re free to disregard if you disagree with it.
Is slide 17 really necessary? Since you go on to finish with a discussion of detector effects and then summarize, but don’t explicitly bring up C(k*) again, it seems a bit extraneous. Also visually it’s interesting because more than half of it is white space (maybe there’s an animation that doesn’t appear in the pdf?) I think if you did want to leave in some discussion about the experimental construction of this observable, it would make sense to include it at the end of slide 12. In my opinion, this would be a good flow: for C(k*) we need theory and experiment — theory should include important details in the calculation as you mention, and experimentally we need an appropriate working definition of the observable, namely the one currently on s. 17. You then get a nice transition to the experimental methods section of the talk which begins on the next slide.

Either way, good luck on the talk!
-Isaac

PS “calcinations” -> “calculations” on s. 20.
