High-energy hyperbolic scattering by neutron stars and black holes
High-energy hyperbolic scattering by neutron stars and black holes
We investigate the hyperbolic scattering of test particles, spinning test particles, and particles with spin-induced quadrupolar structure by a Kerr black hole in the ultrarelativistic regime. We also study how the features of the scattering process modify if the source of the background gravitational field is endowed with a nonzero …
