Title:   “Dark matter stability at fixed points in a modular A_4 symmetry”

Abstract:

Modular flavor symmetries are powerful tools not only to obtain predictions for fermion mass matrices but also to induce dark matter(DM) stability. We propose a new stabilization mechanism for DM at fixed points of modular A_4 symmetry, thanks to the recovery of a residual symmetry for each of fixed points. We find that a model at a fixed point successfully reproduces the neutrino oscillation data without conflict of the DM stability.
