Across-horizon scattering and information transfer — •Viacheslav A. Emelyanov and Frans R. Klinkhamer — Karlsruhe Institute of Technology (KIT) Institute for Theoretical Physics (ITP) Wolfgang-Gaede-Str. 1, 76131 Karlsruhe, Germany

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