摘要：

We investigate B-+/-,B-0 --> rho(0)(omega) h(+/-,0), where rho(0)(omega) decays to pi(+)pi(-) and h is any hadronic final state, such as pi or K. We find large direct CP asymmetry in B meson decays via rho-omega interference. A possible method to determine weak phases, such as phi(2) = arg((VudVub*)/(VtdVtb*)) and phi(3) = arg((VusVub*)/(VtsVtb*)), is also discussed. We show the feasibility to detect the CP asymmetries in these channels by assuming an asymmetric e(+)e(-) collider experiment. 10(9) <B(B)over bar> events are required for the detection of this effect.
