Natural solution of SUSY $\hat{I}¼$ problem from modulus stabilization in modular flavor model

Hong Jie Fan, Fei Wang, Ying Kai Zhang

We propose a solution to the SUSY $\hat{I}¼$-problem within the framework of modular flavor symmetry. The explicit $\hat{I}¼$-term is prohibited by modular symmetry, and an effective $\hat{I}¼$-term…
