TL;DR

This paper investigates the safety and astrophysical implications of hypothetical stable micro black holes produced at a future 100 TeV collider, analyzing their potential risks and constraints from astrophysical observations.

Contribution

It provides a comprehensive analysis of stable micro black hole production, safety considerations, and astrophysical constraints for a 100 TeV collider in theories with large extra dimensions.

Findings

Stable micro black holes could be produced at 100 TeV collider under certain theories.

Astrophysical observations constrain the existence and properties of such micro black holes.

Charged stable micro black holes production is excluded.

Abstract

We study the phenomenology of TeV-scale black holes predicted in theories with large extra dimensions, under the further assumption that they are absolutely stable. Our goal is to present an exhaustive analysis of safety of the proposed 100 TeV collider, as it was done in the case of the LHC. We consider the theories with different number of extra dimensions and identify those for which a possible accretion to macroscopic size would have timescales shorter than the lifetime of the Solar system. We calculate the cross sections of the black hole production at the proposed 100 TeV collider, the fraction of the black holes trapped inside the Earth and the resulting rate of capture inside the Earth via an improved method. We study the astrophysical consequences of stable micro black holes existence, in particular its influence on the stability of white dwarfs and neutron stars. We obtain constraints for the previously unexplored range of higher-dimensional Planck mass values. Several astrophysical scenarios of the micro black hole production, which were not considered before, are taken into account. Finally, using the astrophysical constraints we consider the implications for future 100 TeV terrestrial experiments. We exclude the possibility of the charged stable micro black holes production.
