Study of the semileptonic decays *

Year: 2024

Type: article

Abstract: We study the exclusive semileptonic decays , where . The relevant hadronic form factors are calculated using the covariant confined quark model developed previously by our group. We predict the branching fractions to be of the order of and 10−10 for the case of B and , respectively. Our predictions agree well with other theoretical calculations. We also consider the effects of possible new physics in the case of and show that the branching fraction of this decay can be enhanced by an order of magnitude using constraints from the and experimental data.
