Moments of lepton spectrum in B decays and the mb - mc quark mass difference
Abstract
It is argued that the quark mass difference mb-mc can be extracted with a high accuracy from experimental data on ratia of moments of lepton energy spectrum in semileptonic decays of B mesons. Theoretical expressions for the moments are presented, which include perturbative as well as non-perturbative corrections.
