| contents | We demonstrate that the scalar-mediator dark-matter scenario is consistent with the experimental data on the decay $B\to K M_X$ and provides a good description of the shape of the observed excess. Within this scenario, the interaction with dark-matter particles leads to approximately the same excess in $Γ(B\to K^* M_X)$ and $Γ(B\to K M_X)$ compared to the Standard Model; also the differential distributions of the excess events are similar in shape in the variable $q_\mathrm{rec}^2$ measured by experiment. |
