Hadronic decays of beauty and charm from CLEO

A selection of recent results on hadronic charm and beauty decays from the CLEO experiment are presented. We report preliminary evidence for the existence of final state interactions in B decays and the first observation of the decay B-0 --> D*L+*(-) with a branching fraction of (7.8(-3.8)(+5.4) +/- 1.5) x 10(-4). We also present preliminary results on the first observation of the broad, J(P) = 1(+), charmed meson resonance with a mass of m(D1) ((j=1/2))(0) = 2.461(-0.34)(+0.41)+/-0.010+/-0.032 GeV and a width of Gamma = 290(-79)(+101) +/- 26+/-36 MeV and branching fraction measurements of the B- --> D(J)(0)pi(-1) decay. Finally, we report on our search for the radial excitation of a spin 1 charmed meson, the D*(/+), and on an improved measurement of the ratio of decay rates Gamma(D-0 --> K(+)pi(-))/Gamma(D-0 --> K(-)pi(+)).
