Quantum production of black holes at colliders

TL;DR

This paper explores the potential production of black holes at the LHC within models of extra-dimensional gravity, using horizon quantum mechanics and simulations to predict event rates and mass distributions.

Contribution

It introduces a quantum mechanical approach to black hole production in collider physics, accounting for suppression effects and extra dimensions, and compares predictions with simulations.

Findings

Suppression of black hole production below the fundamental scale

Variation in expected black hole event numbers with extra dimensions

Differences in mass distributions of produced black holes

Abstract

We investigate black hole production in pp collisions at the Large Hadron Collider by employing the horizon quantum mechanics for models of gravity with extra spatial dimensions. This approach can be applied to processes around the fundamental gravitational scale and naturally yields a suppression below the fundamental gravitational scale and for increasing number of extra dimensions. The results of numerical simulations performed with the black hole event generator BLACKMAX are here reported in order to illustrate the main differences in the number of expected black hole events and mass distributions.
