# Complete Michel Parameter Analysis of inclusive semileptonic b o c transition - High Energy Physics - Phenomenology

Abstract: We perform a complete -Michel parameter- analysis of all possible helicitystructures which can appear in the process $B \to X c \ell \bar{ u} \ell$. Wetake into account the full set of operators parametrizing the effectiveHamiltonian and include the complete one-loop QCD corrections as well as thenon-perturbative contributions. The moments of the leptonic energy as well asthe combined moments of the hadronic energy and hadronic invariant mass arecalculated including the non-standard contributions.
