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.

2013 hardware performance evaluation

General

This page will document the testing of new hardware for the 2013 pruchase. For each hardware, several tests will be made as follows:

h-/h+ ratio: 2012 QA

I took a look at the h-/h+ ratio for the 2012 data using code I got from Grant Webb, who had done this for previous years.

Data was from P12id.
