ightarrow K^{ ext{*}0}$ decays within a covariant confined quark model, extending previous work.

## Key findings

- Form factors computed across full kinematic range.
- Results applicable to $B_{s}
ightarrow K^{ ext{*}0}\mu^+\mu^-$ decay analysis.
- Supports experimental measurements by LHCb.

## Abstract

We evaluate $B_{s}\rightarrow K^{\ast 0}$ transition form factors in the full kinematical region within the covariant confined quark model. The calculated form factors can be used to calculate the $B_{s}\rightarrow K^{\ast 0}\mu^+ \mu^-$ rare decay branching ratio, which was recently measured by LHCb collaboration.
