Scattering of massless fermions by Schwarzschild and Reissner-Nordstroem black holes

We study the scattering of massless Dirac fermions by Schwarzschild and Reissner-Nordstroem black holes. This is done by applying partial wave analysis to the scattering modes obtained after solving the massless Dirac equation in the asymptotic regions of the two black hole geometries. We successfully obtain analytic phase shifts, with the help of which the scattering cross section is computed. The glory and spiral scattering phenomena are shown to be present, as in the case of massive fermion scattering by black holes. (author)
