One-loop finite corrections to seesaw neutrino masses

TL;DR

This paper analyzes one-loop finite corrections to neutrino masses in the seesaw model, exploring their dependence on model parameters and potential effects on low-energy neutrino observables.

Contribution

It provides a detailed study of finite one-loop corrections to the neutrino mass matrix within the seesaw framework, highlighting their parameter dependence and phenomenological implications.

Findings

Finite corrections can significantly modify the neutrino mass matrix entries.

Corrections depend on seesaw model parameters such as heavy neutrino masses.

Implications for low-energy neutrino experiments are discussed.

Abstract

In the standard seesaw model, finite corrections to the neutrino mass matrix arise from one-loop self-energy diagrams mediated by heavy neutrinos. We discuss the impact that these corrections may have on the different entries of the tree-level effective neutrino mass matrix, paying special attention to their dependence with the seesaw model parameters. We also briefly comment on the implications these corrections might have on low-energy neutrino observables.
