Minutes of the Neutrino Factory Physics Study Meeting

Present LBL, FNAL, Rochester, Davis, Stonybrook, Brookhaven?

Scribe: Heidi Schellman


1.  News:

  Next meeting is November 9 11:30 CST 12NW/videoland
  Mike Shaevitz is going to try to get a new microphone.

  Request for people to construct bibliographies for oscillation topics
  including probable experimental constraints over the next 5-10 years. 
  Four volunteers, R. Shrock for matter effects, Hitoshi for a review of
  the experimental prospects for the parameter sets generated by Group 3,
  C. Quigg for CP effects, and C. Albright for sterile nus.

  Lyons proceedings are appearing, check at:

2.  Group 1 Beams report - Geer

  Text for preliminary introductory chapter on beam properties
  2/3rds done ... should be completed in 2 weeks ... and maybe
  some version of figures available also.

  Current design assumptions, horizontal = vertical beam divergence
  = 0.1 / gamma.  Momentum spread is 2%.  

3.  Group 3 Oscillations Scenarios - Albright

  Two new scenarios were presented, both with m1 ~ m2 << m3.  These hold
  if LSND  result is not confirmed. This reduces to an effective two
  flavor mixing. The two scenarios have theta13 maximal or < 0.04.

4.  Group 2/4 Detectors/Oscillations 
	
  Bernstein - presented tables in which all possible oscillation
  processes, (example nue->nutau appearance) were classified by
  experimental signatures such as energy spectrum, NC/CC ratio, electron
  appearance…

  Geer showed neutrino rates at a far detector for Scenario 1. Matter
  effects allow the sign of the mass difference to be determined with
  reasonable statistical significance for a 2800 km baseline. 

  Spentzouris showed results of far detector simulation using NuTeV
  detector MC (iron/scintillator sandwich). Showed that charm dimuon
  backgrounds to muon appearance are small compared to Scenario one
  oscillation rates.   

5.  Group 5
	
  Jae Yu  has made a version of Geer’s code adapted for short baseline
  beam ntuple available (version 0.0) see
  http://www.fnal.gov/projects/muon_collider/nu/study/group5/group5.html
  for details.

  Schellman has brief note on near detector beam characteristics, also
  available from Group 5 page.  Near detector beam properties are quite
  different from the familiar far detector ones.
