Analysis of q*2&sub(rec)- Distribution for B *> KM&sub(X) and B*>K&sup(* )M&sub(X) Decays in a Scalar-Mediator Dark-Matter Scenario / A.Berezhnoy, W.Lucha, D.Melikhov. – Text: electronic // Physical Review D. – 2025. – Vol. 111, No. 7. – P. 075035. – URL: https://doi.org/10.1103/PhysRevD.111.075035. – Bibliogr.: 40.

We demonstrate that the scalar-mediator dark-matter scenario is consistent with the experimental data on the decay 𝐵 →𝐾⁢𝑀&sub(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 →𝐾*⁢𝑀&sub(𝑋)) and Γ⁡(𝐵 →𝐾⁢𝑀&sub(𝑋)) compared to the Standard Model; also the differential distributions of the excess events are similar in shape in the variable 𝑞*2&sub(rec) measured by experiment.
