Abstract

In this paper we explore the effects of a Generalized Uncertainty Principle (GUP) on Schwarzschild black hole. In particular, we incorporate the effects of GUP into the Parikh-Wilczek tunneling process for Hawking radiation. To this effect, we observe that results obtained due to GUP correction resemble that of the Reissner-Nordstr\"{om} black hole, showing similarities to the nature of an electric charge. We also find that, within this framework, the emission is not purely thermal, thus addressing the information loss problem through the correlation function.
