“…These studies have demon-strated that the gravitational field can modify the oscillation probability, leading to potentially observable consequences. Examination of neutrino oscillation in curved spacetime is an active area of research with significant implications for astrophysics and cosmology [17,20]. The development of theoretical models that describe the quantum field theory of neutrinos coupled to gravity and the impact of curved spacetime on the oscillation probability have been addressed in several studies (see, for example, [21]).…”

In this paper, we have investigated the mathematical components of the Dirac equation in curved space-time and how it can be applied to the analysis of neutrino oscillations. More specifically, we have developed a method for calculating the phase shift in flavor neutrino oscillations by utilizing a Taylor series expansion of the action, taking into account $\Delta m^4$ orders. In addition, we have used this method to assess how the phase difference in neutrino mass eigenstates changes due to the gravitational field described by the Johannsen spacetime.

We investigate the dynamics of spin-12 particles that are freely propagating in superposed states in curved spacetime. We first make use of a Wentzel-Kramers-Brillouin approximation of the Dirac equation in curved spacetime to extract the corresponding Mathisson-Papapetrou-Dixon equations that describe the deviation from geodesic motion as well as the spin precession of such particles. We then discuss, in light of our results, the case of flavor neutrinos which are, by nature, a superposition of mass eigenstates. Published by the American Physical Society 2024
