论文摘要

在非最小的希格斯框架中,我们提出了一种新型机制,其中违反黑暗颗粒的CP仅通过量规玻色子(主要是$ z $ boson)与SM相互作用。这种$ z $ - 门户的黑暗CP违规是在Higgs介导的(CO)歼灭过程的参数空间的区域中实现的,对DM Relic密度的贡献却可以忽略不计。我们表明,这种违反DM的$ z $ - 竞技CP仍然可以热度并满足所有实验和观察界限,并讨论这种现象对电动eakeak Baryogenogeny的影响。

In a non-minimal Higgs framework, we present a novel mechanism in which the CP violating dark particles only interact with the SM through the gauge bosons, primarily the $Z$ boson. Such $Z$-portal dark CP violation is realised in the regions of the parameter space where Higgs-mediated (co)annihilation processes are sub-dominant and have negligible contributions to the DM relic density. We show that such $Z$-portal CP violating DM can still thermalise and satisfy all experimental and observational bounds and discuss implications of such phenomena for electroweak baryogenesis.
