  • The study of ρ-ω mixing has mainly focused on vector meson decays with isospin I=1, namely the ρ(ω)→π+π- process. In this paper, we present a study of ρ-ω mixing in ρ(ω)→π+π-π0 (I=0) using a flavor parameterization model for the J/ø→ VP process. By fitting a theoretical framework to PDG data, we obtain the SU(3)-breaking effect parameters sV=0.03±0.12, sP=0.17±0.17 and the ρ-ω mixing polarization operator ∏ρω=(0.006±0.011) GeV2. New values are found for the branching ratios when the mixing effect is incorporated: Br(J/ψ→ ωπ0) = (3.64 ±0.37)×10-4, Br(J/ψ→ ωη) = (1.48 ±0.17)×10-3, Br(J/ψ→ ωη') = (1.55±0.56)×10-4, these are different from the corresponding PDG2012 values by 19%, 15% and 15%, respectively.

Abstract: The study of ρ-ω mixing has mainly focused on vector meson decays with isospin I=1, namely the ρ(ω)→π+π- process. In this paper, we present a study of ρ-ω mixing in ρ(ω)→π+π-π0 (I=0) using a flavor parameterization model for the J/ø→ VP process. By fitting a theoretical framework to PDG data, we obtain the SU(3)-breaking effect parameters sV=0.03±0.12, sP=0.17±0.17 and the ρ-ω mixing polarization operator ∏ρω=(0.006±0.011) GeV2. New values are found for the branching ratios when the mixing effect is incorporated: Br(J/ψ→ ωπ0) = (3.64 ±0.37)×10-4, Br(J/ψ→ ωη) = (1.48 ±0.17)×10-3, Br(J/ψ→ ωη') = (1.55±0.56)×10-4, these are different from the corresponding PDG2012 values by 19%, 15% and 15%, respectively.
