Microcanonical treatment of black hole decay at the Large Hadron Collider

TL;DR

This paper investigates microcanonical and back-reaction effects on black hole decay at the LHC, highlighting their potential impact on observable signatures and emphasizing that differences from thermal decay are minimal if new heavy particles are not found.

Contribution

It introduces a microcanonical framework for black hole decay at the LHC, offering a more accurate statistical description of particle emission beyond the canonical approximation.

Findings

Microcanonical corrections are generally small at the LHC.

Differences from thermal decay are negligible if no new heavy particles are discovered.

Provides a statistical interpretation of decay particle densities.

Abstract

This study of corrections to the canonical picture of black hole decay in large extra dimensions examines the effects of back-reaction corrected and microcanonical emission at the LHC. We provide statistical interpretations of the different multiparticle number densities in terms of black hole decay to standard model particles. Provided new heavy particles of mass near the fundamental Planck scale are not discovered, differences between these corrections and thermal decay will be insignificant at the LHC.
