The Solar Neutrino Problem and Gravitationally Induced Long-wavelength Neutrino Oscillation

TL;DR

This paper explores how tiny violations of the weak equivalence principle could cause long-wavelength neutrino oscillations, potentially explaining the solar neutrino problem.

Contribution

It proposes a novel gravitational mechanism for neutrino oscillations that could resolve the solar neutrino problem.

Findings

Gravitationally induced neutrino oscillations can explain the solar neutrino deficit.

The mechanism involves a tiny breakdown of the weak equivalence principle.

The proposed explanation is consistent with existing observations.

Abstract

We have reexamined the possibility of explaining the solar neutrino problem through long-wavelength neutrino oscillations induced by a tiny breakdown of the weak equivalence principle of general relativity. We found that such gravitationally induce oscillations can provide a viable solution to the solar neutrino problem.
