摘要：

Using 1. 16 x 10(6) BBBAR events collected at the UPSILON(4S) resonance by the CLEO Collaboration at the Cornell Electron Storage Ring (CESR), we have searched for decays of B mesons to exclusive two-body hadronic final states including a Ds+ or a D(s)*+ meson. We obtain the 90% confidence level upper limit B(B --> Ds(*)+ pi- + D(s)(*)+ rho- + D(s)(*)+ pi0 + D(s)(*)+ eta + D(s)(*)+ rho0 + D(s)(*)+ omega) x B(D(s)+ --> phipi+) < 1.8 x 10(-5). We have also searched for the W-exchange decays, B0 --> D(s)(*)- K(*)+.
