AI总结:

本文研究含三重态标量的暗物质中微子质量模型,计算残留密度与直接探测约束,并利用 LHC 搜寻限制长寿命双电荷标量质量及未来高亮度灵敏度。

摘要:

中微子质量与暗物质(DM)可能具有共同起源。scotogenic 模型可被视为实现这一想法的原型模型,但还存在许多其他变体。在本文中,我们探索了一个特定的含暗物质中微子质量模型的唯象学,该模型包含一个三重态标量。我们计算了其残留密度,并核查了来自直接探测实验的约束。由这些约束所允许的模型参数空间通常包含一个长寿命或准稳定的双电荷标量,可在 LHC 上进行搜寻。我们重新解释了现有搜寻结果,以推导对模型中标量质量的限制,并估计了 LHC 高亮度阶段的未来灵敏度。我们讨论的搜寻也可用于约束许多其他的 1-loop 中微子质量模型。

英文摘要:

Neutrino masses and dark matter (DM) might have a common origin. The scotogenic model can be considered the proto-type model realizing this idea, but many other variants exist. In this paper we explore the phenomemology of a particular DM neutrino mass model, containing a triplet scalar. We calculate the relic density and check for constraints from direct detection experiments. The parameter space of the model, allowed by these constraints, contains typically a long-lived or quasi-stable doubly charged scalar, that can be searched for at the LHC. We reinterpret existing searches to derive limits on the masses of the scalars of the model and estimate future sensitivities in the high-luminosity phase of the LHC. The searches we discuss can serve to constrain also many other 1-loop neutrino mass models.
