非阿贝尔暗扇区中的多组分暗物质

Multi-Component Dark Matter in a Non-Abelian Dark Sector

Fatemeh Elahi, Sara Khatibi

摘要:

在本文中,我们探讨了一个黑暗的部门的情况下,规范$SU(2)_R$和全球$U(1)_X \times \mathbb{Z}_2$,连续的对称性自发打破全球$U(1)_D$。我们表明,在不同的区域的参数空间,我们可以有两个,或三个暗物质的候选人,这些暗物质粒子是狄拉克费米子,暗规范玻色子,或复杂的标量。这种情况的现象学含义是巨大而有趣的。我们确定的参数空间,考虑到各种实验的约束后,仍然是可行的。我们还讨论了这种情况如何解释DAMPE最近在电子-正电子谱中的观察。此外,我们评论的中微子质量产生之间的标准模型和暗扇区的不可重整化的相互作用。

英文摘要:

In this paper, we explore a dark sector scenario with a gauged $SU(2)_R$ and a global $U(1)_X \times \mathbb{Z}_2$, where the continuous symmetries are spontaneously broken to a global $U(1)_D$. We show that in various regions of the parameter space we can have two, or three dark matter candidates, where these dark matter particles are either a Dirac fermion, a dark gauge boson, or a complex scalar. The phenomenological implications of this scenario are vast and interesting. We identify the parameter space that is still viable after taking into account the constraints from various experiments. We, also, discuss how this scenario can explain the recent observation by DAMPE in the electron-positron spectrum. Furthermore, we comment on the neutrino mass generation through non-renormalizable interactions between the standard model and the dark sector.
