Trimaximal Neutrino Mixing from Modular A4 Invariance with Residual Symmetries

P. P. Novichkov, S. T. Petcov, M. Tanimoto

We construct phenomenologically viable models of lepton masses and mixing based on modular $A_4$ invariance broken to residual symmetries ${\mathbb{Z}}_3^T$ or ${\mathbb{Z}}_3^{ST}$…
