Black hole remnants due to GUP or quantum gravity?

TL;DR

This paper investigates whether black hole remnants are primarily caused by the generalized uncertainty principle (GUP) or quantum gravity effects, using a thought experiment and quantum mechanics considerations.

Contribution

It introduces an analysis based on the running Newton constant to distinguish between GUP and quantum gravity as mechanisms for black hole remnants.

Findings

GUP can lead to black hole remnants of about Planck mass.

Quantum gravity effects are also considered as potential mechanisms.

The analysis provides criteria to differentiate between GUP and quantum gravity effects.

Abstract

Based on the micro-black hole \emph{gedanken} experiment as well as on general considerations of quantum mechanics and gravity the generalized uncertainty principle (GUP) is analyzed by using the running Newton constant. The result is used to decide between the GUP and quantum gravitational effects as a possible mechanism leading to the black hole remnants of about Planck mass.
