具有暗物质和CP破坏的自然多Higgs模型

Natural Multi-Higgs Model with Dark Matter and CP Violation

B. Grzadkowski, O. M. Ogreid, P. Osland

摘要:

我们探讨了惰性双重模型的扩展,它也允许CP破坏在希格斯部门。这需要两个非惰性双峰。惰性双重态中最轻的中性标量是暗物质的候选者。通过参数扫描,我们保留了与WMAP数据一致的暗物质丰度。我们还施加所有相关的对撞机和理论约束,以确定允许的参数空间,其中暗物质是适当的和CP被违反。此外,我们发现的区域,其中的截止的模型源于自然的参数可以大幅提升相比,其标准模型值,达到2-3 TeV。

英文摘要:

We explore an extension of the Inert Doublet Model which allows also for CP violation in the Higgs sector. This necessitates two non-inert doublets. The lightest neutral scalar of the inert doublet is a candidate for dark matter. Scanning over parameters we preserve the abundance of the dark matter in agreement with the WMAP data. We also impose all relevant collider and theoretical constraints to determine the allowed parameter space for which both the dark matter is appropriate and CP is violated. In addition we find regions where the cut-off of the model originating from naturality arguments can be substantially lifted compared to its Standard Model value, reaching 2-3 TeV.
