It introduces a model connecting near-horizon Planck-scale modifications to quantum gravity corrections in black hole tunneling processes.
Findings
Corrections to emission probabilities can arise from modifications of surface gravity.
Planck-scale effects may lead to higher order quantum gravity corrections.
The work links Lorentz invariance departures with black hole entropy corrections.
Abstract
The emergence of quantum-gravity induced corrective terms for the probability of emission of a particle from a black hole in the Parikh-Wilczek tunneling framework is studied. It is shown, in particular, how corrections might arise from modifications of the surface gravity due to near horizon Planck-scale effects. Our derivation provides an example of the possible linking between Planck-scale departures from Lorentz invariance and the appearance of higher order quantum gravity corrections in the black-hole entropy-area relation.
