abstract

We study the radiative corrections to the stabilization of the complex structure modulus $\tau$ in modular flavor symmetric models. We discuss the possibility of obtaining the vacuum expectation value of $\tau$ in the vicinity of the fixed point where residual symmetries remain unbroken. As concrete examples, we analyze the 1-loop Coleman-Weinberg potential in the $A_4$ modular flavor models. We show that the 1-loop correction may lead to the slight deviation from the tree level result, which may realize a phenomenologically preferred value of the complex structure modulus $\tau$ particularly when the number of species contributing to the 1-loop correction is large enough.
