Left-Right model with radiative double seesaw mechanism
We propose an extended Left-Right symmetric model with an additional global U(1)X symmetry, which collapses to a residual subgroup ℤ2 after spontaneous symmetry breaking. In this model, the light active neutrino masses are generated via a double seesaw mechanism with the Dirac submatrix arising at one loop. In addition, the masses of the charged fermions of the Standard Model (SM) that are lighter
