Minimum length effects in black hole physics

TL;DR

This paper reviews how a fundamental minimum length scale influences black hole physics, including effects on black hole mass, Hawking radiation, and potential observable signatures in models with extra dimensions.

Contribution

It provides a comprehensive analysis of minimum length effects on black hole properties and Hawking decay, including in higher-dimensional models with phenomenological implications.

Findings

Minimum black hole mass is affected by quantum length scale.

Modified dispersion relations alter Hawking radiation characteristics.

Extra-dimensional models may produce observable signatures.

Abstract

We review the main consequences of the possible existence of a minimum measurable length, of the order of the Planck scale, on quantum effects occurring in black hole physics. In particular, we focus on the ensuing minimum mass for black holes and how modified dispersion relations affect the Hawking decay, both in four space-time dimensions and in models with extra spatial dimensions. In the latter case, we briefly discuss possible phenomenological signatures.
