Black Holes and Quantum Gravity at the LHC

TL;DR

This paper challenges the likelihood of black hole signatures at the LHC and suggests that if the quantum gravity scale is low, higher-dimensional quantum gravity could be explored through compositeness searches.

Contribution

It proposes that black hole signatures are unlikely and highlights the potential for studying quantum gravity via compositeness searches at the LHC.

Findings

Black hole signatures are very unlikely in current models.

Higher-dimensional quantum gravity can be probed through compositeness searches.

Limited parameter regimes for black hole detection at the LHC.

Abstract

We argue that the highly studied black hole signatures based on thermal multiparticle final states are very unlikely and only occur in a very limited parameter regime if at all. However, we show that if the higher-dimensional quantum gravity scale is low, it should be possible to study quantum gravity in the context of higher dimensions through detailed compositeness-type searches.
