NLO corrections to power suppressed contributions to B→ Xcℓν — Thomas Mannel, Alexei A. Pivovarov, and •Denis Rosenthal — Theoretische Physik 1, Naturwissenschaftlich-Technische Fakultät, Universität Siegen, Walter-Flex-Straße 3, D-57068 Siegen, Germany
The study of inclusive B-meson decays is useful to extract information of the standard model’s flavor structure. For this we use the heavy quark expansion, a systematic, QCD-based expansion in inverse powers of a single heavy quark mQ. In particular, we compute NLO perturbative corrections to power suppressed contributions of order 1/mQ2 to the total width B→ Xcℓν.
