Strong decay patterns of the 1-+ exotic hybrid mesons

We calculate the coupling constants of the decay modes 1-+→ρπ, f1π, b1π, ηπ, η'π, a1π, f1η within the framework of the light-cone QCD sum rule. Then we calculate the partial width of these decay channels, which differ greatly from the existing calculations using phenomenological models. For the isovector 1-+ state, the dominant decay modes are ρπ, f1π. For its isoscalar partner, its dominant decay mode is a1π. We also discuss the possible search of the 1-+ state at BESIII, for example through the decay chains J/ψ(ψ')→π1+γ or J/ψ(ψ')→π1+ρ, where π1 can be reconstructed through the decay modes π1→ρπ→π+π-π0 or π1→f1(1285)π0. Hopefully the present work will be helpful to the experimental establishment of the 1-+ hybrid meson.
