Semileptonics

oral

We report on recent exclusive semileptonic B decay results from BaBar. We get the total branching fractions for the decay channels : B --> pi ell nu, B --> rho ell nu, B --> eta(') ell nu and B --> Ds K ell nu_bar. From the partial branching fractions measured in the B --> pi ell nu channel, we obtain values of the CKM matrix element |V_{ub}| using three different QCD calculations.

88. D, Ds Leptonic decays and form factors

Semileptonics

oral

We review recent measurements of leptonic decays of D mesons and compare the results on the decay constants with Lattice QCD calculations.

Semileptonics

oral

Charmless semileptonic decays provide information on the Cabibbo-Kobayashi-Maskawa matrix element |Vub|, which plays a crucial role in testing the description of quark mixing phenomenology, including CP violation. |Vub| is currently measured with inclusive charmless semileptonic decays, and with exclusive semileptonic decays, with results which do not agree very well. It is of great interest...
