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-
Invariant Masses
- High mass tails due to incorrect photon reconstruction have been removed. These tails were due to photons in the FCAL being reconstructed with vertex-z = 0, such that they had bogus momentum vectors. This was fixed when Miha Kornicer recently updated the photon reconstruction code.
- Pi0 invariant mass:
- X(2000) invariant mass:
