Hadronic B Decays To Charm From CLEO
  Recent results include the measurement of B->D(*)pi+pi-pi-pi0 decays, with rates of ~1.8% observation of a significant omega pi^- substructure that appears to result from the decay of the rho' resonance, whose mass and width we determine as 1418 MeV and 382 MeV, respectively. Using B to charmonium decays we find that the neutral B fraction in Y(4S) decays is nearly half, that the CP asymmetries in J/\psi K^(-/+) and psi' K^(-/+) are small, and we also report on the first observation of B->eta_c K.
