Abstract

Data are presented on the reaction J/ψ → pp̄η using 7.8 × 10⁶ J/ψ triggers collected by the BEjing Spectrometer (BES). A partial wave analysis is performed. A clear enhancement near the pη(p̄η) threshold is observed. It is fitted with a J^P = 1/2^- resonance with mass M = 1530 ± 10 MeV and width Γ = 95 ± 25 MeV. In addition, there is a peak around 1650 MeV with J^P = 1/2^- preferred also, fitted with M = 1647 ± 20 MeV and Γ = 145_-45⁺⁸⁰ MeV. These two N* resonances are believed to be the two well established states, S₁₁(1535) and S₁₁(1650), respectively. It is the first partial wave study of the production of these resonances from J/ψ decays.

N2 - Data are presented on the reaction J/ψ → pp̄η using 7.8 × 106 J/ψ triggers collected by the BEjing Spectrometer (BES). A partial wave analysis is performed. A clear enhancement near the pη(p̄η) threshold is observed. It is fitted with a JP = 1/2- resonance with mass M = 1530 ± 10 MeV and width Γ = 95 ± 25 MeV. In addition, there is a peak around 1650 MeV with JP = 1/2- preferred also, fitted with M = 1647 ± 20 MeV and Γ = 145-45+80 MeV. These two N* resonances are believed to be the two well established states, S11(1535) and S11(1650), respectively. It is the first partial wave study of the production of these resonances from J/ψ decays.
