Quasi-Classical Gravity Effect on Neutrino Oscillations in a Gravitational Field of a Heavy Astrophysical Object

Figure 3

Differential cross section of the gravitational Bethe-Heitler scattering of neutrino off a massive object, for example, a black hole (BH) in radiated graviton energy (a), in polar angle of the final-state neutrino (b), and the integrated cross section as a function of incoming neutrino energy typical for astrophysical sources, for example, see [69], (c).
