STAR HardProbes PWG

[Barbara Trzeciak <barbara.trzeciak AT gmail.com>]

Hi Rachael,

please find below my comment on your nice slides.

- s5: for physics motivation, I would suggest adding here some existing results on J/psi production vs multiplicity.

- s5: add also information that you measure J/psi via the dimuon decay 

- s8: it's quite busy, try to reduce the text or I would also suggest to move: "Particle identification (PID) cuts on ∆TOF, DCA, ∆z, ∆y∗q, and mass applied" and the sub-bullets to a separate slide. You mention these requirements and the MTD matching which are important for your muon identification - I think they deserve more explanation (even than the nSigmaPion) to people and maybe you can add some plots. I'm missing information related to MTD (you could also consider describing more the detector itself). 

- s10: looks that you're still missing text here

- s11: Add information how you determine the background

- s12: through the invariant mass of the decay -> through the invariant mass of the decayed muons

Cheers,

Barbara

Hi Rachael,

    These are nice slides. Please find a few comments from me below. I sign off with them implemented

S4: Figure overlaps test on left

S5, 2nd bullet: Shouldnt this be multiplicity dependence of quarkonia yields?

S5: Using data from p + p collisions 

S7: TPC clusters --> TPC hits

S7: Remove 'applied to blue and teal nHitsFit, nHitsDedx,and nHitsRatio'

S7: On the plot change labels to match text, cuts --> track quality cuts, matching --> MTD matching

S7: Last bullet: Instead of current one better to briefly describe what MTD matching means

S8: Is the DeltaTOF here from MTD? Better to indicate that

S9: Do you need both slides 9 and 10? Doesnt S10 suffice?

S11: using crystal ball function for the mass peak

S11: Do you exclude the Psi(2S) mass region when fitting?

S12: QA is more a STAR lingo. Also what do you mean pT spectra allows to identify muon candidates? Better to summarize which detecctors/quantities have been used in muon identification

S13: I dont think for STAR talks we give personal acknowledgements to STAR Collaborators for their contribution to the talk/results

thanks

Hello Rachael,

Please find my comments on your nice presentation slides.

Slide5: "       Using p + p at 510 GeV from 2017 " -> "Using p + p at
$sqrt($s$)=510 GeV from 2017 data taking"
Slide6:  please mention vx, vy, and vr; Include dataset information in
plot
Slide7:Include dataset information in plot
Slide8: Include dataset information in plot;
Slide9: Include dataset information in plot
