sPHENIX is a new detector at RHIC.

Hi all,

we are planning to finalize our thoughts on the descoping impact on "Cold QCD / Medium Energy Physics" measurements at the Cold QCD topical group meeting tonight at 8:30 pm EDT.

Best,

Nils

All,

nicely written document! Some remarks...

I cannot claim that I have been at every meeting, but I don't recall
seeing the 15%-ish *increase* in efficiency in Fig 1.3 (right) at low z
values. This large difference just between the instrumented and
non-instrumented setups (where no instrumentation seems better) is
somewhat counter-intuitive to my eye.

Rosi presented John's distributions in slightly different form at the
Oct 6 fortnightly meeting, and there it looked less pronounced (in both
cases the green curve). Also there the low-z enhancement was in the
charged leading particle plot, neutral was flat, opposite of fig. 1.3.
Is there a simple explanation why one would expect that?


In line 114 the arrow in Y-> e+e- points the wrong way.

My 5cts,

        Martin
