论文摘要
如果暗物质（DM）粒子的稳定性是由于意外对称性引起的，那么没有什么可以阻止紫外线通过诱导紫外线量表抑制的DM衰变来破坏它的稳定。 Seesaw物理学，大概是中微子质量的起源，可能会引起这种腐烂。我们表明，如果Seesaw量表位于通常的Weinberg操作员尺度周围，那么诱导的DM衰减可能会导致中微线，其强度的强度为中微子望远镜的当前灵敏度。我们通过模型来说明这种可能性，其中DM由Abelian或非阿布莱尔仪表对称性的仪表玻色子制成。
If the stability of the dark matter (DM) particle is due to an accidental symmetry, nothing prevents UV physics from destabilising it by inducing DM decays suppressed by powers of the UV scale. The seesaw physics, presumably at the origin of neutrino mass, could induce such a decay. We show that if the seesaw scale lies around the usual Weinberg operator scale, the induced DM decay could generically lead to neutrino lines whose intensity is of the order of the present sensitivity of neutrino telescopes. We illustrate this possibility with models in which the DM is made of the gauge boson(s) of an abelian or non-abelian gauge symmetry.
