摘要

我们证明了标量介质暗物质场景与B→KMX衰变的实验数据是一致的，并且很好地描述了观测到的过量的形状。在这种情况下，与暗物质粒子的相互作用导致Γ（B→K*MX）和Γ（B→KMX）与标准模型相比大致相同的过剩；在实验测量的变量qrec2中，过量事件的微分分布在形状上也很相似。2025年由美国物理学会出版

Analysis of qrec2 -distribution for B→KMX and B→K*MX decays in a scalar-mediator dark-matter scenario
We demonstrate that the scalar-mediator dark-matter scenario is consistent with the experimental data on the decay B→KMX 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*MX) and Γ(B→KMX) compared to the Standard Model; also the differential distributions of the excess events are similar in shape in the variable qrec2 measured by experiment.
