A proposal on the search for the hybrid with $I^G(J^{PC})=1^-(1^{-+})$ in the process $J/\psi o ho\omega\pi\pi$ at upgraded BEPC/BES

摘要

The moment expressions for the boson resonances X with spin-parity 0++, 1-+,1++, and 2++ possibly produced in the process $J/\psi\to\rho X$, $X\tob_1(1235)\pi$, $b_1\to \omega \pi$ are given in terms of the generalized momentanalysis method. The 1-+ resonance can be distinguished from other resonancesby means of these moments except for some rather special cases. The suggestionthat the search for the 1-+ hybrid can be performed in the above decay channelat upgraded BEPC/BES is presented.
