Hadronic Decays of Beauty and Charm from CLEO
Abstract
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 B0 -> D*+D*- with a branching fraction of (6.2^{+4.0}_{-2.9}+/- 1.0)x10^{-4}. We also present preliminary results on the first observation of the broad, J^P=1^+, charmed meson resonance with a mass of 2.461^{+0.041}_{-0.034}+/-0.010+/-0.032 GeV and a width of 290^{+101}_{-79}+/-26+/-36 MeV and branching fraction measurements of the B- -> D_J^0pi- decays. Finally, we report on search for the radial excitation of a spin 1 charmed meson, the D*'+, and on an improved measurement of the ratio of (D0 -> K+pi-)/(D0 -> K-pi^+) decay rates.

A modified version of this paper was published in the proceedings of the "Workshop on Heavy Quarks at Fixes Targets" held at FermiLab on October 10 through the 12, 1998. This version includes a correction to the value of the B->D*+D*- branching fraction and two figures were added to the section on the D*' analysis. Also, an error in the reported statistical error of the mass of the broad D_J resonance was corrected. The reported value in the previous version of this paper was a factor of 10 larger than the measured value
