Moments of lepton spectrum in {ital B} decays and the {ital m}{sub {ital b}}{minus}{ital m}{sub {ital c}} quark mass difference
- Theoretical Physics Institute, University of Minnesota, Minneapolis, Minnesota 55455 (United States)
It is argued that the quark mass difference {ital m}{sub {ital b}}{minus}{ital m}{sub {ital c}} can be extracted with a high accuracy from experimental data on ratios of moments of the lepton energy spectrum in semileptonic decays of {ital B} mesons. Theoretical expressions for the moments are presented, which include perturbative as well as nonperturbative corrections.
