Dynamical generation of neutrino mass scales
Alfredo Aranda, Cesar Bonilla, Eduardo Peinado
TL;DR
This paper proposes a model where atmospheric and solar neutrino mass scales are generated dynamically through separate mechanisms, a type-I seesaw and a radiative loop, establishing a relation between the two scales.
Contribution
It introduces a novel scenario combining a type-I seesaw and a radiative process to explain neutrino mass scales with a linked relation.
Findings
Two independent mechanisms generate neutrino mass scales.
A relation between the atmospheric and solar neutrino scales is derived.
The model offers a unified explanation for neutrino oscillation data.
Abstract
In this letter we present a simple scenario where the mass scales associated to atmospheric and solar neutrino oscillations are obtained through the dynamical generation of neutrino masses. The main idea is that the two different scales are the result of two independent mechanisms, namely a type-I seesaw generating the atmospheric scale and a radiative 1-loop process providing the solar one. A relation of the two scales, reminiscent of the so-called sequential dominance, is thus obtained.
