• 題目: A scotogenic model with a non-invertible $Z_ M$ symmetry

概要

In this talk, we discuss a scotogenic model applying non-invertible $Z_ M$ symmetries. Firstly we review neutrino mass models and global flavor symmetries. Then we discuss construction of a scotogenic model with a non-invertible $Z_ M$ symmetry. The stability of dark matter and the scotogenic structure of the neutrino mass matrix is achieved via the new non-group symmetry. We explore minimalistic structure of a scotogenic model in our scheme giving a one-zero structure of the neutrino mass matrix, and numerical analysis of the lepton mixing angles and some predictions are presented.
