Black Hole Production at the Large Hadron Collider

TL;DR

This paper explores the potential for black hole production at the LHC within TeV-scale gravity models, analyzing how factors like electric charge influence production rates and the implications for fundamental physics parameters.

Contribution

It provides new estimates of lower limits on the Planck scale at LHC energies and investigates the impact of parton electric charge on black hole production cross-sections.

Findings

Electric charge can reduce black hole cross-section by up to four orders of magnitude.

Lower limits on the Planck scale depend on the accuracy of the production cross-section.

Charge effects are significant and must be considered in black hole production predictions.

Abstract

Black hole production at the Large Hadron Collider (LHC) is an interesting consequence of TeV-scale gravity models. The predicted values, or lower limits, for the fundamental Planck scale and number of extra dimensions will depend directly on the accuracy of the black hole production cross-section. We give a range of lower limits on the fundamental Planck scale that could be obtained at LHC energies. In addition, we examine the effects of parton electric charge on black hole production using the trapped-surface approach of general relativity. Accounting for electric charge of the partons could reduce the black hole cross-section by one to four orders of magnitude at the LHC.
