Possible scenario for MaVaN's as the only neutrino flavor conversion mechanism in the Sun

TL;DR

This paper explores the hypothesis that MaVaN's could be the sole mechanism for neutrino flavor conversion in the Sun, linking neutrino mass variations to environmental baryonic density effects.

Contribution

It introduces a parameterization of environmental effects on neutrino mass that can explain observed flavor conversion probabilities in solar and terrestrial experiments.

Findings

Mass Varying neutrino mechanisms can account for flavor conversions.

Environmental dependence of neutrino mass reproduces experimental data.

MaVaN's could be the only flavor conversion mechanism in the Sun.

Abstract

Mass Varying neutrino mechanisms were proposed to link the neutrino mass scale with dark energy, addressing the coincidence problem. In some scenarios this mass can present a dependence on the baryonic density felt by neutrinos, creating an effective neutrino mass that depends both on the neutrino and baryonic densities. In this article we investigate the possibility that a neutrino effective mass is the only flavour conversion mechanism acting in neutrino oscillation experiments. We present a parameterization on the environmental effects on neutrino mass that produces the right flavour conversion probabilities for solar and terrestrial neutrinos experiments.
