Supersymmetry versus black holes at the LHC

TL;DR

This paper proposes a method to distinguish supersymmetry from black hole events at the LHC by analyzing isolated leptons and event-shape variables, demonstrating that dilepton invariant mass is a key signature.

Contribution

The study introduces a simple, effective approach using dilepton invariant mass and event-shape analysis to differentiate supersymmetry and black hole signals at the LHC.

Findings

Dilepton invariant mass effectively distinguishes supersymmetry from black hole events.

Event-shape variables and multilepton events support the discrimination method.

Black hole and supersymmetry events show distinct signatures in LHC data.

Abstract

Supersymmetry and extra dimensions are the two most promising candidates for new physics at the TeV scale. Supersymmetric particles or extra-dimensional effects could soon be observed at the Large Hadron Collider. We propose a simple but powerful method to discriminate the two models: the analysis of isolated leptons with high transverse momentum. Black hole events are simulated with the CATFISH black hole generator. Supersymmetry simulations use a combination of PYTHIA and ISAJET, the latter providing the mass spectrum. Our results show the measure of the dilepton invariant mass provides a strong signature to differentiate supersymmetry and black hole events at the Large Hadron Collider. Analysis of event-shape variables and multilepton events complement and strengthen this conclusion.
