Are neutrino masses dynamically generated by quantum gravity attractions?

TL;DR

This paper proposes that quantum gravity effects dynamically generate tiny neutrino masses, leading to a predictive framework for neutrino mass splittings and mixings within the Standard Model.

Contribution

It introduces a novel mechanism where quantum gravity attractions produce neutrino masses, connecting gravity to neutrino phenomenology in a predictive manner.

Findings

Neutrino masses are generated by quantum gravity attractions.

The model predicts neutrino mass splittings and mixing angles.

Implications for Standard Model and quantum gravity compatibility.

Abstract

It is argued that the quantum gravity attractions dynamically generate tiny degenerate Majorana masses for the neutrinos. The unequal masses of the charged leptons then induce a computable neutrino mass matrix with splittings and mixings through the electroweak interactions. In this way the Standard Model including quantum gravity can accommodate and predict the neutrino masses and mixings. Some consequences are pointed out.
