Prospects for the sensitivity from E949-2002 (calculating )

E787 1gamma analysis:

• = (after prescaled by 2450)
• S.E.S( , wpigg) =

E949 March-April6: (conservative number)

• 1gamma prescaled by 512 in smx, 1520 events/spill
• = (after prescaled by 512)
  This is already comparable to E787-1gamma.
• This sample should be useful for
  • photon inefficiency study,
  • search for rare decays (, ..)
    with the tagged 's from decays.

E949 April19-May: 4 weeks

• per four-hour shift
  (conservative number from SteveK)
• 6 shifts per day and 28 days in total.
  This is the bottom line.
• = (after prescaled by 512)
  This is of the E787-1gamma sample.
• S.E.S( , wpigg) = from = .
  This is larger than the ChPT prediction:
  B( , wpigg) = .
