Quantum gravity corrections to the tunneling radiation of scalar particles

TL;DR

This paper explores how quantum gravity effects, modeled via the generalized uncertainty principle, modify the tunneling radiation of scalar particles from black holes, leading to slower temperature increase and the formation of remnants.

Contribution

It introduces quantum gravity corrections into the tunneling radiation process, revealing their impact on black hole temperature evolution and remnant formation.

Findings

Quantum gravity effects slow down black hole temperature increase.

Remnants are formed during black hole evaporation.

Hawking temperature depends on quantum numbers of emitted particles.

Abstract

The original derivation of Hawking radiation shows the complete evaporation of black holes. However, theories of quantum gravity predict the existence of the minimal observable length. In this paper, we investigate the tunneling radiation of the scalar particles by introducing quantum gravity effects influenced by the generalized uncertainty principle. The Hawking temperatures are not only determined by the properties of the black holes, but also affected by the quantum numbers of the emitted particles. The quantum gravity corrections slow down the increase of the temperatures. The remnants are found during the evaporation.
