A4 lepton flavor model and modulus stabilization from S4 modular symmetry
Abstract
We study the modulus stabilization in an A4 model whose A4 flavor symmetry is originated from the S4 modular symmetry. We can stabilize the modulus so that the A4 invariant superpotential leads to the realistic lepton masses and mixing angles. We also discuss the phenomenological aspect of the present model as a consequence of the modulus stabilization.
