论文摘要
我们研究磁化轨道模型中的模块化对称性异常。诸如D-Brane Instanton效应之类的非扰动效应可能会破坏树级对称性。我们研究了三代中微子的主要质量术语明确折断模块对称的部分。中微子质量项的模块化重量与树级拉格朗日中的其他耦合项不匹配。此外，模块化风味对称性的$ z_n $对称性被打破，并且模块化风味对称性的某个正常亚组仍处于中微子质量方面。
We study the modular symmetry anomaly in magnetized orbifold models. The non-perturbative effects such as D-brane instanton effects can break tree-level symmetry. We study which part of the modular symmetry is broken explicitly by Majorana mass terms with three generations of neutrinos. The modular weight of neutrino mass terms does not match with other coupling terms in tree-level Lagrangian. In addition, the $Z_N$ symmetry of the modular flavor symmetry is broken and a certain normal subgroup of the modular flavor symmetry remains in neutrino mass terms.
