Update on Hist vs Func Templates

In my talk for today's (Feb 7, 2013) Spin PWG phone meeting, it was noted and discussed that the uncertainty for the longitudinal spin asymmetries is much higher using histogram rather than functional templates.  One additional point has been noted: alpha (the data/MC energy scale factor) was not fixed for the spin fits as it should.  Here's updated results (plus a whole lot more plots).

Repeat of Cut Review

This is basically a repeat of the most salient parts of the Feb. 1st "Review of Cuts" blog, given the fitting updates of the Feb. 5 "Another Updated Fit" blog.  These results were discussed in the PWG phone meeting today (Feb 7th, 2013), and this blog is the promised further details.  The conclusions of the discussions are that
  • The cross section is not very sensitive to these cuts
  • While the mass plots look nices, it appears the MC fits work comparably well for any cut choice
  • The high cost of cutting statistics is not sufficiencly offset by reductions in systematics, and thus no cuts will be changed.

Remaining items on my single-beam background wish-list are to examine the mass distribution for events without a BBC-coincidence, quantify the percentage which pass our cuts, and examine the φ-

Note: during the meeting it was noted that the text above the plots on slide 6 were wrong.  This is now fixed.
