Y(2175) Study
Reaction
- γ p → Y(2175), p
- Y(2175) → π+, π-, φ
- φ → K+, K-
- Y(2175) → π+, π-, φ
- Final State: p, π+, π-, K+, K-
- ~530,000 Events Generated using genr8 with: 9 GeV Photons, ΓY(2175) = 61 MeV/c2, t-slope = 5.0, 50.0 < Vertex-Z (cm) < 80.0
Background Channel
- γ p → f1(1285), p
- f1(1285) → π+, π-, π+, π-
- NOTE: had to trick genr8 by having the f1(1285) decay to η, η, and then each decaying to π+, π-
- Final State: p, π+, π-, π+, π-
- ~530,000 Events Generated using genr8 with: 9 GeV Photons, Γf1(1285) = 24 MeV/c2, t-slope = 5.0, 50.0 < Vertex-Z (cm) < 80.0
