Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

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.
