摘要

本文讨论了由中微子散射引起的轫致辐射。这个过程应该存在，因为中微子预计会通过磁偶极子和跃迁矩与光子耦合。这些力矩是由环路引起的，在具有中微子质量的标准模型中很小，但在扩展理论中可以显着增强。作为具体的例子，我们研究了地球上两个最大的中微子通量，太阳中微子和宇宙中微子背景(CNB)的散射。人们很容易认为这是CNB搜索的一个潜在特征，但事实证明，这个信号非常小，不太可能被观察到。

Bremsstrahlung from Neutrino Scattering via Magnetic Dipole Moments

In this paper, we discuss bremsstrahlung induced by neutrino scattering. This process should exist since neutrinos are expected to couple to photons via magnetic dipole and transition moments. These moments are loop-induced and tiny in the Standard Model with neutrino masses but could be significantly enhanced in extended theories. As concrete example, we study the scattering of the two largest neutrino fluxes on earth, solar neutrinos and Cosmic Neutrino Background (CNB). It is tempting to consider this as a potential signature for CNB searches but it turns out that the signal is extremely small and unlikely to be observed.
