Radiative seesaw in left-right symmetric model

TL;DR

This paper explores how radiative processes in left-right symmetric models can generate neutrino masses, potentially surpassing traditional tree-level seesaw mechanisms and aligning with observed neutrino data.

Contribution

It demonstrates that radiative contributions in left-right symmetric models can dominate over tree-level seesaw, offering a new perspective on neutrino mass generation.

Findings

Radiative contributions can dominate over tree-level seesaw.

Radiative mechanisms can explain observed neutrino masses.

Left-right symmetric models accommodate radiative neutrino mass generation.

Abstract

There are some radiative origins for the neutrino masses in the conventional left-right symmetric models with the usual bi-doublet and triplet Higgs scalars. These radiative contributions could dominate over the tree-level seesaw and could explain the observed neutrino masses.
