Across-horizon scattering and information transfer.

F.R. Klinkhamer, V.A. Emelyanov

We address the question whether or not two electrically charged particles can Coulomb scatter if one of these particles is inside a Schwarzschild black-hole horizon and the other outside. We show that the quantum process is consistent with the local energy-momentum conservation law. This result implies that across-horizon scattering is a physical effect, happening near astrophysical black holes. Using the quantum scattering process, we propose a Gedankenexperiment which transfers information from inside the black-hole horizon to outside.
