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
- # Photons per Event
- # π+'s per Event
- # π-'s per Event
- # Protons per Event
Invariant Masses
π0
- π0: Filled for all events with > 1 photon, filled for all possible photon combinations (so if three photons in an event, will fill 3 times).
- # Events with at least one π0 candidate: 57866 with sim-recon-2011-03-31, 31071 with code from 05-24-11 at 16:11 (but photon P & E = 0!!)
ρ0
- ρ0: Filled for all events with at least one π+ and at least one π-, filled for all possible pion combinations (so if two π+'s and two π-'s in an event, will fill 4 times).
- # Events with at least one ρ0 candidate: 58466 with sim-recon-2011-03-31, 59178 with code from 05-24-11 at 16:11
ω
- ω: Filled for all events with at least: one π+, one π-, and two photons. Filled for all possible ρ0 combinations, but for events with multiple π0 candidates the π0 with the closest mass was chosen.
- # Events with at least one ω candidate: 31012 with sim-recon-2011-03-31
b1
- b1: Filled for all events with at least: two π+'s, one π-, and two photons. Filled for all possible combinations of these tracks (regardless of which π+ formed the ρ0).
- # Events with at least one b1 candidate: 12163 with sim-recon-2011-03-31
X(2000)0
- X(2000)0: Filled for all events with at least: two π+'s, two π-'s, and two photons. Filled for all possible combinations of these tracks (regardless of which π+ & π- formed the Rho0).
- # Events with at least one X(2000)0 candidate: 4760 with sim-recon-2011-03-31
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:
