高尺度跷跷板相互作用引起的DM衰变的中微子谱线

Neutrino lines from DM decay induced by high-scale seesaw interactions

Rupert Coy, Thomas Hambye

摘要:

如果暗物质(DM)粒子的稳定性是由于偶然的对称性,那么没有什么能阻止紫外物理学通过诱导被紫外尺度的幂抑制的DM衰变来破坏它。跷跷板物理学,大概是中微子质量的起源,可以引起这样的衰变。我们表明,如果跷跷板规模位于通常的温伯格运营商规模,诱导DM衰变一般会导致中微子线的强度是目前的中微子望远镜的灵敏度的顺序。我们用模型来说明这种可能性,在模型中,DM是由阿贝尔或非阿贝尔规范对称性的规范玻色子组成的。

英文摘要:

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.
