Hawking Radiation via Tunnelling from Arbitrarily Dimensional Schwarzschild Black Holes

We extend Parikh’s recent work to the arbitrarily dimensional Schwarzschild black holes whose Arnowitt--Deser--Misner (ADM) mass is identical to its mass parameter. We view Hawking radiation as a tunnelling process across the event horizon. From the tunnelling probability we also find a leading correction to the semiclassical emission rate. The result consists with an underlying unitary theory.
