TL;DR

This paper investigates brane-world stars and microscopic black holes, deriving black hole metrics with tidal charge, and establishing a minimum mass for microscopic black holes relevant to LHC experiments.

Contribution

It introduces a method to determine the tidal charge as a function of black hole mass in brane-world models, linking black hole metrics to observable phenomena.

Findings

Recovery of brane-world black hole metrics with tidal charge

Implications for black hole detection at the LHC

Abstract

We study stars in the brane-world by employing the principle of minimal geometric deformation and find that brane-world black hole metrics with a tidal charge are consistently recovered in a suitable limit. This procedure allows us to determine the tidal charge as a function of the black hole ADM mass (and brane tension). A minimum mass for semiclassical microscopic black holes can then be derived, with a relevant impact for the description of black hole events at the LHC.
