b1pi Overview
- Generated 10000 X(2000) -> b1π-; events following the instructions here.
- Decay chain:
gamma p -> p X(2000)0 | |-> b1(1235)+ π- | |-> ω π+ | |-> ρ0 π0 | |-> γ γ | |-> π+ π-
b1pi 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

Problems: - Storing final track information in DVertex subclasses is non-intuitive (especially the 2D track_info_t vector). - DVertex::track_info_t does not inherit from JObject: cannot add associated objects (DTOFPoint, etc.) - Cannot call JEventLoop->Get(DVertex::track_info_t) (No factories for the particles) - All neutral particles are assumed to be photons (could be neutrons, such as from Lambda decay).
