Production and evaporation of Planck scale black holes at the LHC

TL;DR

This paper reviews the potential production and evaporation of Planck-scale black holes at the LHC, highlighting how quantum gravity effects influence their signatures and the current non-observation constraints.

Contribution

It introduces an improved production cross-section model and explores quantum corrections, suggesting black holes could form near LHC energies with distinctive soft particle emissions.

Findings

Current non-observation explained by quantum gravity effects

Black holes could form at energies slightly above LHC design

Emission predominantly consists of soft particles on the brane

Abstract

We review the phenomenology of mini black holes at colliders in light of the latest data from the LHC. By improving the conventional production cross-section, we show that the current non-observation of black hole signals can be explained in terms of quantum gravity effects. In the most optimistic case, black hole production could take place at a scale slightly above the LHC design energy. We also analyse possible new signatures of quantum-corrected Planck-scale black holes: in contrast to the semiclassical scenario the emission would take place in terms of soft particles mostly on the brane.
