Combining theory inputs for BD(*)nu and extracting |Vcb|Marzia Bordone1,2, Martin Jung3, and •Danny van Dyk41Physik-Institut, Universität Zürich, Winterthurer Strasse 190, 8057 Zürich, Switzerland — 2Theoretische Physik 1, Universität Siegen, Walter-Flex-Straße 3, D-57068 Siegen, Germany — 3Excellence Cluster Universe, Technische Universität München, Boltzmannstr. 2, D-85748 Garching, Germany — 4Physik Department, TU München, James-Franck-Straße 1, D-85748 Garching, Germany

Recent theory results for the full set of hadronic matrix elements arising in BD(*)ν decays have triggered our interest. We investigate if and how various pieces of theory information on these hadronic matrix elements fit together. As a consequence, we obtain precise theory predictions for the full angular distribution of these decays in the SM and beyond. Finally, we challenge the experimental data available from the BaBar and Belle collaborations. We discuss the compatibility between our results for |Vcb| and the inclusive determination.
