Overview
- Generated 100000 X(2000) -> b1π-; events following the instructions here.
- Except ran by linking against the sim-recon-2011-03-31 build. All plots & statistics are from this build unless indicated otherwise.
- Decay chain:
gamma p -> p X(2000)0
|
|-> b1(1235)+ π-
|
|-> ω π+
|
|-> ρ0 π0
| |-> γ γ
|
|-> π+ π-
Event Count
# Generated events = 100000 # Events with 2+ photons = 57866 # Events with 2+ π+'s = 29372 # Events with 2+ π-'s = 30634 # Events with enough tracks for the X (2+ photons, 2+ π+'s, 2+ π-'s) = 4760 # Events with at least one π0 candidate: 57866 # Events with at least one ρ0 candidate: 58466 # Events with at least one ω candidate: 31012 # Events with at least one b1 candidate: 12163 # Events with at least one X(2000)0 candidate: 4760

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:
