Some decay modes of the $1^{-+}$ hybrid meson in QCD sum rules revisited

Abstract

The pionic coupling constants in the decays of the $1^{-+}$ hybrid meson are calculated. The double Borel transformation is invoked and continuum contribution is subtracted. The decay widths of the processes $1^{-+}\to \rho \pi ,f_1\pi ,\pi \gamma$ are around $40,100,0.3$ MeV respectively.
