Event Count
# Generated events = 10000 # Events with 2+ photons = 9660 # Events with 2+ π+'s = 7642 # Events with 2+ π-'s = 8156 # Events with 2+ protons = 1040 (should only be 1 !!) # Events with enough tracks for the X (2+ photons, 2+ π+'s, 2+ π-'s) = 6076
Invariant Masses
Comparison of Generated and Reconstructed Tracks
- NOTE: There was no observed φ-dependence on track reconstruction distributions.
γ's
- p vs θ distributions for the generated & reconstructed photons:
π+'s
- p vs θ distributions for the generated & reconstructed π+'s:
π-'s
- p vs θ distributions for the generated & reconstructed π-'s:
p's
- p vs θ distributions for the generated & reconstructed protons:
