A spin-parity analysis of the ωπ0 enhancement photoproduced in the energy range 20 to 70 GeV
1984
Abstract A study is made of the ωπ 0 system produced near threshold in the reaction γ p→ π + π − π 0 π 0 p. A spin-parity analysis shows that the ωπ 0 enhancement is consistent with predominant 1 + B(1235) production, with ∼20% J P = 1 − background.
