Complete Michel Parameter Analysis of inclusive semileptonic b \to c transition

Abstract

We perform a complete "Michel parameter" analysis of all possible helicity structures which can appear in the process $B\to X_c\ell {\bar{\nu }}_{\ell }$. We take into account the full set of operators parametrizing the effective Hamiltonian and include the complete one-loop QCD corrections as well as the non-perturbative contributions. The moments of the leptonic energy as well as the combined moments of the hadronic energy and hadronic invariant mass are calculated including the non-standard contributions.

22 pages, 3 figures, non-perturbative corrections added
