Minutes

  1. Eugene reported on the committee recommendation to study the impact (e.g. resolution, e.m. background) of a reduced solenoid current of 1300/1350 nA on various physics channels. Aristeidis Tsaris volunteered to perform some initial studies. It was discussed to use the 3π channel and some of the strange final states in last year's PAC proposal.
  2. Paul M. discussed his plans for skimming the data challenge data and his studies on the "gain" of different cuts in skimming the files.
  3. Mike Staib gave a presentation on the Kinematic Fitter updates. The acceptance has generally improved for many channels.
  4. No updates on the PAC proposal; Simon Taylor presented some acceptance studies on η → 3π which is still somewhat lower than expected.
  5. Kevin Bauer (IU) presented his η'π+n channel (η → γπ+π-) study which is geared toward an undergraduate thesis.
  6. Justin Steven's practice talk was moved to Tuesday, April 22nd, 2:30 PM.
