QCD sum rules analysis of the B_(s)to D_(sJ)(2460)lν decay
read the original abstract
Using three point QCD sum rules method, the form factors relevant to the semileptonic $B_{s}\to D_{sJ}(2460)\ell\nu$ decay are calculated. The $q^2$ dependencies of these form factors are evaluated. The dependence of the asymmetry parameter $\alpha$, characterizing the polarization of $D_{sJ}$ meson, on $q^2$ is studied. This study gives useful information about the structure of the $D_{sJ}$ meson. Finally the branching ratio of this decay is also estimated and is shown that it can be easily detected at LHC.

Semileptonic B decays to mixed axial-vector mesons show branching ratios and polarization observables that vary strongly with the D1 mixing angle in the covariant light-front quark model.

Semileptonic B to axial-vector meson decays are studied as functions of the mixing angle θ_D1 using covariant light-front quark model form factors, producing predictions for branching ratios, forward-backward asymmetr...
