TL;DR

This paper investigates how quantum gravity effects, modeled by natural cutoffs, influence particle tunneling from black hole horizons and their implications for information loss.

Contribution

It introduces a framework incorporating minimal length, momentum, and maximal momentum to analyze tunneling and correlations in black hole radiation.

Findings

Natural cutoffs modify tunneling rates.

Correlations between emitted particles are affected.

Quantum gravity effects influence information retrieval.

Abstract

We study tunneling of massless particles through quantum horizon of a Schwarzschild black hole where quantum gravity effects are taken into account. These effects are encoded in the existence of natural cutoffs as a minimal length, a minimal momentum and a maximal momentum through a generalized uncertainty principle. We study possible correlations between emitted particles to address the information loss problem. We focus also on the role played by these natural cutoffs on the tunneling rate through quantum horizon.
