|V_ub| and |V_cb| from CLEO
arXiv:hep-ex/0307011
Abstract
We report on studies of exclusive and inclusive semileptonic b -> ulνand b -> clνdecays in 9.7 million B\barB events accumulated with the CLEO detector in symmetric e^+e^- collisions produced in the Cornell Electron Storage Ring (CESR). Various experimental techniques, including the inference of neutrino candidates using the hermeticity of the CLEO detector and the study of spectral moments, are used in conjunction with theoretical calculations to provide estimates of the CKM matrix elements |V_ub| and |V_cb|.
