Extracting Vub Using the Radiative Decay Data
Ira Z. Rothstein
Abstract
In this talk I review recent progress made in extracting Vub from the cut electron energy and hadronic mass spectra of inclusive B meson decays utilizing the data from radiative decays. It is shown that an extraction is possible without modeling the B meson structure function. I discuss the issues involving the assumptions of local duality in various extractions. I also comment on the recent CLEO extraction of Vub.
