We study the rare semileptonic decays of Bc mesons within the effective field theoretical framework of covariant confined quark model. The transition form factors corresponding to Bc+→D(∗)+ and Bc+→Ds(∗)+ are computed in the entire q2 range. Using form factors, we compute the branching fractions and compare them with the available theoretical results. We also compute various physical observables such as forward-backward asymmetry, longitudinal and transverse polarizations, as well as clean angular observables.

Abstract
We study the rare semileptonic decays of Bc mesons within the effective field theoretical framework of covariant confined quark model. The transition form factors corresponding to Bc+→D(∗)+ and Bc+→Ds(∗)+ are computed in the entire q2 range. Using form factors, we compute the branching fractions and compare them with the available theoretical results. We also compute various physical observables such as forward-backward asymmetry, longitudinal and transverse polarizations, as well as clean angular observables.| File | Dimensione | Formato | |
