Using a WKB approximation of the Dirac equation in a curved spacetime, we obtain the expression for the phase shift between two neutrino mass eigenstates in a generic gravitational field. We apply this expression to two specific space-time geometries, namely the Kerr–Newman metric describing a rotating and charged black hole, and the Friedmann–Robertson–Walker metric.

Abstract
Using a WKB approximation of the Dirac equation in a curved spacetime, we obtain the expression for the phase shift between two neutrino mass eigenstates in a generic gravitational field. We apply this expression to two specific space-time geometries, namely the Kerr–Newman metric describing a rotating and charged black hole, and the Friedmann–Robertson–Walker metric.File in questo prodotto:
