Semileptonic B_(s) rightarrow D_(s2)^(*)(2573)ellbar{ν}_(ell) transition in QCD
read the original abstract
We analyze the semileptonic $ B_{s} \rightarrow D_{s2}^{*}(2573)\ell\bar{\nu }_{\ell}$ transition, where $\ell=\tau,~\mu$ or $e$, within the standard model. We apply the QCD sum rule approach to calculate the transition form factors entering the low energy Hamiltonian defining this channel. The fit functions of the form factors are used to estimate the total decay widths and branching fractions in all lepton channels. The orders of branching ratios indicate that this transition is accessible at LHCb in near future.

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...
