Abstract

The CLEO detector is located at the CESR e+e- collider in Ithaca, NY. CLEO's wide range of experimental measurements in b-hadron decays is represented by improved measurements of Vcb and Vub, rare B decays, and bb-bar spectroscopy. New experimental results in exclusive hadronic transitions will aid theorists in developing a theory of hadronic B decays. Such a theory will have consequences for the extraction of angles of the unitarity triangle, especially gamma. Recently, the CLEO collaboration has shifted its focus towards precision measurements at lower energies. Based on the new Y(3S) data, we present the observation of a new bound bb-bar state. An outlook on the planned running at tau/charm-energies (CLEO-c) is given and implications for b-physics are discussed.
