超神冈的暗物质-中微子耦合的意义

Implications of a Dark Matter-Neutrino Coupling at Hyper-Kamiokande

Andres Olivares-Del Campo, Sergio Palomares-Ruiz, Silvia Pascoli

摘要:

暗物质和中微子为粒子物理学的标准模型之外的新物理学提供了两个最令人信服的证据,但它们通常被视为两个不同的部门。在本文中,我们考虑如何中微子可观测量可以用来约束不同的模型的参数空间,其中活跃的中微子与DM通过不同的自旋介质相互作用。首次研究了超神冈探测器对MeV暗物质湮灭产生的中微子的灵敏度。特别是,我们发现,热产生的DM候选人之间的质量15-30兆电子伏可以完全排除。

英文摘要:

Dark matter and neutrinos provide the two most compelling pieces of evidence for new physics beyond the Standard Model of Particle Physics but they are often treated as two different sectors. In this paper, we consider how neutrino observables can be used to constrain the parameter space of different models where active neutrinos interact with DM via mediators of different spins. We study for the first time the sensitivity of the Hyper-Kamiokande detector to neutrinos produced from MeV Dark Matter annihilation. In particular, we find that thermally produced DM candidates with masses between 15-30 MeV could be fully excluded.
