论文摘要
我们指出，如果存在光（伪）标量介体，则中微子可以增强与光子的耦合，从而导致潜在的可测量中微子极化。我们表明，小型中微子肿块的预期抑制可以通过轻中微子质量来补偿，从而在低尺度上产生尺寸7瑞利操作员。我们探索了此类模型的丰富现象学，并详细介绍了对可行参数空间的约束，这是由中微子与中微子和光子的耦合所跨越的。最后，我们构建了几个明确的模型，通过修改倒数远见Maparon，即$ U（1）_l $ Global Lepton号码负责产生小型中微子质量的伪 - nambu-goldstone-Boson，从而导致中微子的极化性增强。
We point out that neutrinos can have enhanced couplings to photons, if light (pseudo)scalar mediators are present, resulting in potentially measurable neutrino polarizability. We show that the expected suppression from small neutrino masses can be compensated by the light mediator mass, generating dimension 7 Rayleigh operators at low scales. We explore the rich phenomenology of such models, computing in details the constraints on the viable parameter space, spanned by the couplings of the mediator to neutrinos and photons. Finally, we build several explicit models that lead to enhanced neutrino polarizability by modifying the inverse see-saw majoron, i.e., the pseudo-Nambu-Goldstone boson of the $U(1)_L$ global lepton number responsible for generating small neutrino masses.
