A proposal on the search for the hybrid with I-G(J(PC))=1(-)(1(-+)) in theprocess J/psi -> rho omega pi pi at upgraded BEPC/BES

We give the moment expressions for the boson resonances X with spin-parity J(X)(PxC) = 0(++), 1(-+), 1(++) and 2(++) possibly produced in the process J/psi --> rhoX, X --> b(1) (1235)pi, b(1) --> omega pi in terms of the gene ralized moment analysis method. The resonance with J(X)(PxC) = 1(-+) can be distinguished fi om other resonances by means of these moments except for some rather special cases. The suggestion that the search for the hybrid wi th I-G(J(PC)) = 1(-)(1(-+)) can be performed in the decay channel J/psi, -- > rho omega pi pi at upgraded BEPC/BES is presented.
