论文摘要
我们研究了标准模型（SM）的扩展，其中sm-higgs Doublet的两个副本不会获得真空期望值，因此添加了{\ it intert}。惰性部门的最轻粒子是可行的暗物质候选者。我们允许在这个扩展的黑暗部门中进行CP侵犯，并在几个基准方案中评估$ ZZZ $顶点及其CP侵入性外形。我们以潜在的可观察到的不对称性和横截面的形式提供了这种深色CP侵略的对撞机签名，该形式的$ f \ bar f \ to z^*\ to z^*\ to zz $在Leptonic和Hadroonic Machines上都可以观察到。
We study an extension of the Standard Model (SM) in which two copies of the SM-Higgs doublet which do not acquire a vacuum expectation value, and hence are {\it inert}, are added to the scalar sector. The lightest particle from the inert sector, which is protected from decaying to SM particles through the conservation of a $Z_2$ symmetry, is a viable dark matter candidate. We allow for CP-violation in this extended dark sector and evaluate the $ZZZ$ vertex and its CP-violating form factor in several benchmark scenarios. We provide collider signatures of this dark CP-violation in the form of potentially observable asymmetries and cross sections for the $f\bar f\to Z^*\to ZZ$ process at both leptonic and hadronic machines.
