Abstract

The moment expressions for the boson resonances X with spin-parity 0++, 1-+, 1++, and 2++ possibly produced in the process $J / I ¨ \to I ¨ X$ , $X \to b_{1} (1235) I ¨ $ , $b_{1} \to I ¨ I ¨ $ are given in terms of the generalized moment analysis method. The 1-+ resonance can be distinguished from other resonances by means of these moments except for some rather special cases. The suggestion that the search for the 1-+ hybrid can be performed in the above decay channel at upgraded BEPC/BES is presented.
