Neutrino oscillations in curved spacetime: an heuristic treatment
read the original abstract
We discuss neutrino oscillations in curved spacetime. Our heuristic approach can accomodate matter effects and gravitational contributions to neutrino spin precession in the presence of a magnetic field. By way of illustration, we perform explicit calculations in the Schwarzschild geometry. In this case, gravitational effects on neutrino oscillations are intimately related to the redshift. We discuss how spacetime curvature could affect the resonance position and adiabaticity of matter-enhanced neutrino flavor conversion.

Mass Varying Neutrino Oscillation in Teleparallel Gravity
Torsion-coupled scalar in teleparallel gravity induces density-dependent neutrino masses that alter MSW resonance and yield constraints on coupling parameters from Super-Kamiokande, Borexino and SNO data.
