Particle Phenomenology of Gravitational Events at the TeV Scale

TL;DR

This paper explores the potential production of microscopic black holes at the TeV scale in particle colliders, comparing their signatures with other new physics models like supersymmetry and extra dimensions.

Contribution

It presents simulation-based methods to distinguish black hole events from other beyond Standard Model phenomena using high transverse momentum particles and event shape analysis.

Findings

High transverse momentum leptons differentiate black holes from supersymmetry.

High transverse momentum Z0 bosons and photons distinguish black holes from string resonances.

Event shape variables enhance discrimination of different new physics models.

Abstract

If the fundamental scale of gravity is of the order of 1 TeV, black holes might be produced at the Large Hadron Collider. This work presents simulations of black holes and other exotic models of physics beyond the Standard Model - supersymmetry, extra dimensional models and string theory. Isolated leptons with high transverse momenta can be used to distinguish black holes from supersymmetry and models of extra dimensions. Z0 bosons and photons with high transverse momenta allow the discrimination of black holes and string resonances. The analysis of visible and missing energy/momenta and event shape variables complement these techniques.
