Study of b -> u l nu Decays with an Inclusive Generator
Abstract
Description
A generator for inclusive b -> u l nu decays has been developed. Different prescriptions have been applied to describe the kinematics of the b-quark inside the hadron and the generation of the hadronic final states. Results are presented with particular attention to the invariant mass of the hadronic system recoiling against the lepton and its resonance decomposition. These studies are of special relevance for the extraction of Vub from semileptonic B decays at LEP and at B factories.
