Hawking radiation of charged particles as tunneling from Reissner–Nordström–de Sitter black holes with a global monopole

Abstract

Applying Parikh's semi-classical tunneling method, we consider Hawking radiation of the charged massive particles as a tunneling process from the Reissner–Nordström–de Sitter black hole with a global monopole. The result shows that the tunneling rate is related to the change of Bekenstein–Hawking entropy and the radiant spectrum is not a pure thermal one, but is consistent with an underlying unitary theory.
