Pseudoscalar-Meson Mixing in J/ψ Decays

  • Based on the bracnhing fractions of J/ψ→VP, γP quoted in PDG-2000, we reexamined the quark content of pseudoscalars. If there is no gluonium content in η and η′, the mixing angle θP=(-19.18±0.91)°. We also present a discussion for DOZI contribution, SU(3) breaking and scalar-meson mixing.

Abstract: Based on the bracnhing fractions of J/ψ→VP, γP quoted in PDG-2000, we reexamined the quark content of pseudoscalars. If there is no gluonium content in η and η′, the mixing angle θP=(-19.18±0.91)°. We also present a discussion for DOZI contribution, SU(3) breaking and scalar-meson mixing.
