Description

Symmetries have played a central role in understanding the structure of particle interactions, especially in flavor physics. Recently, non-invertible symmetries, described by fusion algebras instead of conventional groups, have opened a new direction in model building.
I will present a radiative neutrino mass model based on some non-invertible fusion rules. The framework provides a novel selection rule that differs fundamentally from ordinary discrete symmetries and leads to a naturally loop-induced neutrino mass. I will highlight how non-invertible structures can offer new perspectives on flavor model building and discuss possible phenomenological consequences.
