Inclusive spectra in charmless semileptonic B decays by Dressed Gluon Exponentiation

Abstract

The triple differential spectrum in B̄ −→ Xulν̄ is computed by Dressed Gluon Exponentiation (DGE). In this framework the on-shell calculation, converted into hadronic variables, can be directly used as an approximation to the meson decay spectrum, without involving a leading–power non-perturbative function. Sudakov resummation for the fully differential B… (More)
