论文摘要
我们研究模块化对称方法的框架中的模量稳定问题。 By analysing simple UV-motivated CP-invariant potentials for the modulus $τ$ we find that a class of these potentials has (non-fine-tuned) CP-breaking minima in the vicinity of the point of $\mathbb{Z}_3^{ST}$ residual symmetry, $τ\simeq e^{2πi/3}$.稳定模量在这些新颖的最小值上会自发地打破CP对称性，并且自然可以解释带电的瘦素和夸克的质量层次结构。
We study the problem of modulus stabilisation in the framework of the modular symmetry approach to the flavour problem. By analysing simple UV-motivated CP-invariant potentials for the modulus $τ$ we find that a class of these potentials has (non-fine-tuned) CP-breaking minima in the vicinity of the point of $\mathbb{Z}_3^{ST}$ residual symmetry, $τ\simeq e^{2πi/3}$. Stabilising the modulus at these novel minima breaks spontaneously the CP symmetry and can naturally explain the mass hierarchies of charged leptons and possibly of quarks.
