中微子自相互作用

Neutrino Self-Interactions

Jasper Hasenkamp

摘要:

我们提出了一个理论,该理论认为活跃中微子之间的相互作用至少比弱相互作用强三个数量级。引入了具有真空期望值$v_x \lesssim \mathcal{O}(100 \textrm{ MeV})$的阿贝尔规范群$U(1)_x$.非对称质量矩阵将活动中微子实现为携带“有效”电荷的无质量本征态。为了稳定$v_x$,超对称性破缺是通过环介导的,只有xHiggs项除外。没有标准模型相互作用本征态携带$U(1)_x$电荷。因此,暗光子的动力学混合被双圈抑制,我们的理论可以用简单而通用的无量纲参数来解释IceCube观测到的高能中微子谱,包括PeV中微子。我们评论的实施机会,将自我相互作用的暗物质候选人。

英文摘要:

We propose a theory that equips the active neutrinos with interactions among themselves that are at least three orders of magnitude stronger than the weak interaction. We introduce an Abelian gauge group $U(1)_x$ with vacuum expectation value $v_x \lesssim \mathcal{O}(100 \textrm{ MeV})$. An asymmetric mass matrix implements the active neutrinos as massless mass eigenstates carrying "effective" charges. To stabilize $v_x$, supersymmetry breaking is mediated via loops to the additional sector with the only exception of xHiggs terms. No Standard Model interaction eigenstate carries $U(1)_x$ charge. Thus the dark photon's kinetic mixing is two-loop suppressed.With only simple and generic values of dimensionless parameters, our theory might explain the high-energy neutrino spectrum observed by IceCube including the PeV neutrinos. We comment on the imposing opportunity to incorporate a self-interacting dark matter candidate.
