论文摘要
我们研究了由电子和中微子之间的模量或Flavon交换引起的标量非标准中微子相互作用（NSI）。在具有非变化电子密度的区域中，已知它们确定中微子质量基质的变化。我们审查并扩展了相关形式主义，并更新了电子和中微子标量耦合的现有限制。我们探讨了基于风味对称性的Lepton Masses模型中标量NSI的可观察性。我们分析了标量耦合受到阿贝尔对称性或模块化不变性约束的模型。我们强调了可能发生可观察效应的参数空间区域。
We study scalar Non-Standard Neutrino Interactions (NSI) induced by moduli or flavon exchange between electrons and neutrinos. In a region with non-vanishing electron number density, they are known to determine a shift of the neutrino mass matrix. We review and extend the relevant formalism, and we update the existing limits on electron and neutrino scalar couplings. We explore the observability of scalar NSI in models of lepton masses based on flavour symmetries. We analyze models where the scalar couplings are constrained either by abelian symmetries or by modular invariance. We highlight regions of the parameter space where observable effects can occur.
