A radiatively induced inverse seesaw model with hidden U(1) gauge symmetry

A radiatively induced inverse seesaw model with hidden U(1) gauge symmetry

We propose an inverse seesaw scenario under hidden $U(1)$ gauge symmetry, having rather natural hierarchies among neutral fermion mass scales. The hierarchies are derived from theory and experimental constraints. The theory requires Majorana exotic masses have to be induced at one-loop level. The experimental side requests that the Dirac mass …
