$$B_{s}^{0} \to \bar {K}{\text{*}}{{(892)}^{0}}{{\ell }^{ + }}{{\ell }^{ - }}$$ Decay in Covariant Confined Quark Model

Аннотация

The $$B_{s}^{0} \to \bar {K}{\text{*}}{{(892)}^{0}}{{\ell }^{ + }}{{\ell }^{ - }}$$ rare decays was studied in the framework of the covariant confined quark model. We calculated the $$B_{s}^{0} \to \bar {K}{{{\text{*}}}^{0}}$$ transition form factors in the entire dynamical range of momentum transfer squared. Using the form factors, we computed the branching fractions of the rare decays and our results are found to be matching well with the experimental data. We compared our results for form factors and branching fractions with results from other theoretical approaches.
