Inverse seesaw model with large SU(2)L multiplets and natural mass hierarchy
We propose an inverse seesaw model with large SU(2)L multiplet fields which realizes natural mass hierarchies among neutral fermions. Here, lighter neutral fermion mass matrices are induced via two suppression mechanisms; one is small vacuum expectation value of SU(2)L triplet required by rho parame...
