A radiative type-II seesaw model with broken symmetry ansatz

Parametrization of the neutrino mass matrix in terms of well-known measured quantities is an attractive way to obtain a phenomenologically viable form. We propose a model of neutrino mass matrix based on type-II seesaw mechanism adhering the concept of badly broken symmetry. Two of the mixing angles are coming out as theta(23) similar to 46.08 degrees, theta(13) similar to 8.69 degrees. However, to accommodate the other oscillation parameters, we further add an extra doublet and the neutrino masses are generated through the Zee mechanism at the one loop level, and the modified model can admit all the extant data for a suitable choice of model parameters.

Automated summary

The study proposes a model of neutrino mass matrix based on the type-II Seesaw mechanism and concept of badly broken symmetry, with the addition of an extra doublet and use of the Zee mechanism for neutrino mass generation. This modified model can accommodate all existing data by selecting suitable model parameters.
