sPHENIX is a new detector at RHIC.

Hi Dennis,

Thanks for the feedback. I updated the slides accordingly except the following two points:

-For Slide 8, do you think I should bump this to the back up slides or just keep your comment in mind?

-I double checked with Rosi about the EPD status and she wants to make sure the ink is fully dry before announcing it officially anywhere but I think I can say verbally more than what I have on the slide though.

Best,

-Megan

Hi Megan,

Thanks for the draft of what looks like an excellent talk!

Please consider just a handful of comments, since I know time is limited before your talk:

slide 6 - If you have space/time for it, I like to stress that the calorimeters allow for unbiased, efficient triggering in p+p. Having a large-statistics sample of p+p reference data will be a key advantage for sPHENIX both in making real data-to-data RAAs and in understanding the jet energy scale just in p+p collisions.

slide 11 - Instead of “Tracking system provides improved energy response”, you might sell the main benefits of Particle Flow as, e.g. “Tracking information reduces sensitivity to fragmentation, better allows sub-structure measurements” (since one can always correct calo jets for the average response)

slide 21 - The Event Plane Detector is no longer simply “Proposed” - it is funded by an NSF MRI!

slides 24 and 25 - Are these theoretical calculations within the SCET_G framework? If so, you might label them as such, since people at the workshop may recognize that better than “pQCD” (which is a bit more mysterious)

More granular comments: 

slide 8 - For these particular kinematics, the effect on the JER is actually pretty modest, because the “separation” in the response between different phi-Psi_2 regions is smaller than the intrinsic resolution in any particular region.

slide 9 - I would flip the two bullet points (the expected “ordering” is in the JER at low-pT)

Dear all,

Sorry for the extremely late posting. I was invited to present at the INT workshop. The talk is today at 1pm ET. My slides are at the attached link. Thank you if you get a chance to look and comment before then and thanks to Rosi for the overnight feedback. Again apologies for the late posting.

Thanks,

-Megan
