Procedure

  • Reconstruct π(1600) -> b1π events with t-slope = 2.0 using both the 334 and 1234 segmentations
  • Plot Δβ vs p for π+ candidates to see proton, π+ separation.

π(1600) -> b1pi Events

p vs. θ

  • p vs. θ
    • NOTE: time improvement only at forward angles, so will be negligible for protons in this reaction.
π+'s
protons

π+ BCAL Δβ vs p

Δβ = βp - βt = p/sqrt(p*p + m*m) - path/(c*TOF)

334 Segmentation


  • π(1600) -> b1pi Events, π+ Candidates, BCAL Δβ vs p
p = 1.2 GeV/c, 334 Segmentation
p = 1.4 GeV/c, 334 Segmentation
p = 1.5 GeV/c, 334 Segmentation
p = 1.6 GeV/c, 334 Segmentation
