轻子双Higgs偶态模型中的标量暗物质

Scalar Dark Matter in Leptophilic Two-Higgs-Doublet Model

Priyotosh Bandyopadhyay, Eung Jin Chun, Rusa Mandal

摘要:

在大的$\tanβ$极限下,X型双Higgs模型变为亲轻子模型,产生轻赝标$A$,从而解释了μ子$g-2$反常现象.在这种情况下,引入一个单线标量暗物质$S$,人们发现,两个重要的暗物质的属性,核子散射和自湮灭,分别由单独的耦合暗物质的两个希格斯双峰。虽然这两个耦合之一是强烈的直接检测实验的约束,另一个仍然是自由的调整,主要是通过过程$SS\to AA$的遗物密度。这导致了$4τ$的最终状态,可以通过银河伽马射线探测探测。

英文摘要:

Two-Higgs-Doublet Model of Type-X in the large $\tanβ$ limit becomes leptophilic to allow a light pseudo-scalar $A$ and thus provides an explanation of the muon $g-2$ anomaly. Introducing a singlet scalar dark matter $S$ in this context, one finds that two important dark matter properties, nucleonic scattering and self-annihilation, are featured separately by individual couplings of dark matter to the two Higgs doublets. While one of the two couplings is strongly constrained by direct detection experiments, the other remains free to be adjusted for the relic density mainly through the process $SS\to AA$. This leads to the $4τ$ final states which can be probed by galactic gamma ray detections.
