Suppressed Black Hole Production from Minimal Length

TL;DR

This paper investigates how the concept of a minimal length in quantum gravity theories suppresses the expected production of black holes in models with large extra dimensions, affecting potential experimental signatures.

Contribution

It introduces the impact of minimal length effects on black hole production rates in theories with large extra dimensions, a novel consideration in this context.

Findings

Minimal length effects suppress black hole production rates.

The suppression alters expected experimental signatures.

Implications for future collider searches.

Abstract

Large extra dimensions lower the Planck scale to values soon accessible. Motivated by string theory, the models of large extra dimensions predict a vast number of new effects in the energy range of the lowered Planck scale, among them the production of TeV-mass black holes. But not only is the Planck scale the energy scale at which effects of modified gravity become important. String theory as well as noncommutative quantum mechanics suggest that the Planck length acts a a minimal length in nature, providing a natural ultraviolet cutoff and a limit to the possible resolution of spacetime. The minimal length effects thus become important in the same energy range in which the black holes are expected to form. In this paper we examine the influence of the minimal length on the expected production rate of the black holes.
