Title: Possible scenario for MaVaN's as the only neutrino flavor conversion mechanism in the Sun
Author: de Holanda, PC
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 in matter in addition to a very small mass squared difference in vacuum (O(10(-9) eV(2))) are the main 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.
