Oscillations, Neutrino Masses and Scales of New Physics

TL;DR

This paper demonstrates that current neutrino experimental data can be explained by models where neutrinos are massless at tree level but acquire small Dirac masses through radiative corrections, suggesting a potential mechanism for neutrino mass generation.

Contribution

It introduces a framework where neutrino masses arise from radiative corrections in existing models, providing an alternative to traditional mass generation mechanisms.

Findings

Neutrino data compatible with zero tree-level mass models

Neutrinos gain small Dirac masses via radiative corrections

Supports radiative correction as a viable neutrino mass mechanism

Abstract

We show that all the available experimental information involving neutrinos can be accounted for within the framework of already existing models where neutrinos have zero mass at tree level, but obtain a small Dirac mass by radiative corrections.
