Black Holes at the LHC

TL;DR

This paper discusses the theoretical possibility and observable signatures of small black holes potentially created in particle collisions at the LHC within higher-dimensional models, focusing on their formation, properties, and Hawking radiation emissions.

Contribution

It provides a comprehensive overview of the assumptions, criteria, and methods for studying black hole creation and evaporation in collider experiments within higher-dimensional theories.

Findings

Current models predict observable Hawking radiation signatures.

Methodologies for detecting black-hole events at LHC are outlined.

Properties of black holes formed in high-energy collisions are analyzed.

Abstract

In these two lectures, we will address the topic of the creation of small black holes during particle collisions in a ground-based accelerator, such as LHC, in the context of a higher-dimensional theory. We will cover the main assumptions, criteria and estimates for their creation, and we will discuss their properties after their formation. The most important observable effect associated with their creation is likely to be the emission of Hawking radiation during their evaporation process. After presenting the mathematical formalism for its study, we will review the current results for the emission of particles both on the brane and in the bulk. We will finish with a discussion of the methodology that will be used to study these spectra, and the observable signatures that will help us identify the black-hole events.
