论文摘要
我们提出了一种复合暗物质（DM）的模型，其中一种新的QCD型限制“ HyperColor”扇区会产生自然稳定的高音型候选物作为DM候选者，同时为新的弱耦合玻色子$ H $提供了质量，该效率是DM介体，将Hyperbaryons用作DM介体，将Hyperbaryons与标准模型（Smsmsmsmsmsmsmssmplaryions couplions couplions）。通过适当的选择，将$ h $量规的对称作为水平$ su（2）_h $ sm sm symmetry，我们展示了如何使用最近提出的水平量规玻色子来识别$ h $仪表玻色子，以解释在稀有$ $ b $ -meson衰减中差异的解释。我们发现，DM现象学提出的$ H $量规玻色子的质量比例与解释罕见的$ b $ -DECAY差异所需的一致。
We present a model of composite Dark Matter (DM), in which a new QCD-like confining "hypercolor" sector generates naturally stable hyperbaryons as DM candidates and at the same time provides mass to new weakly coupled gauge bosons $H$ that serve as DM mediators, coupling the hyperbaryons to the Standard Model (SM) fermions. By an appropriate choice of the $H$ gauge symmetry as a horizontal $SU(2)_h$ SM flavor symmetry, we show how the $H$ gauge bosons can be identified with the horizontal gauge bosons recently put forward as an explanation for discrepancies in rare $B$-meson decays. We find that the mass scale of the $H$ gauge bosons suggested by the DM phenomenology intriguingly agrees with the one needed to explain the rare $B$-decay discrepancies.
