sPHENIX discussion of physics

[Gunther M Roland <rolandg AT mit.edu>]

Hi Sarah,

Looks good!  A few minor comments:

s4: The “LHC more gluon dominated” statement describes the plots shown, but that may be more a matter of the horizontal scale chosen than the underlying physics. Once we go closer to the kinematic limit at LHC, jets there will also be quark-dominated (I think with the 2015 data, 1TeV is possible).

s7: "Trigger with no jet bias” -> maybe “Jets without trigger bias” would be clearer

s11: This is more heavily inspired by ATLAS than CMS. The CMS strategy is a bit confusing, at the moment

s12: This is without any jet ID cuts (e.g. requiring a moderate pT charged particle)?

s14: I’m not sure I understand the “600B rare trigger events”? Are these “600B events sampled by calorimeter triggers”? I think we may try to get rid of those by shrinking the interaction diamond (to be discussed)…

s21: If there’s time expanding a bit on the b-tagging (with e.g. a purity vs efficiency ROC plot and some statements about the need for high precision vertexing) would be nice

Cheers,

Gunther
