QCD effects on "stable" micro black holes at the LHC

TL;DR

This paper investigates hypothetical stable micro black holes at the LHC, focusing on QCD effects and pion emission during accretion, concluding such black holes would escape Earth and pose no danger.

Contribution

It introduces the concept of stable MBHs with non-decaying behavior and analyzes QCD effects on their accretion and resulting dynamics.

Findings

Pion emission occurs during nucleon accretion by stable MBHs.

Accretion leads to a recoil velocity sufficient for MBHs to escape Earth.

Stable MBHs are unlikely to be dangerous due to their escape velocity.

Abstract

If Micro Black Holes (MBHs) can be produced at the LHC, they will decay very fast. We study hypothetical MBHs that do not decay; in particular, QCD effects on accretion by MBHs that are produced at rest. We explain why accretion of a nucleon by such MBHs is associated with pion emission. This pion emission results in a kick to the MBHs, such that their velocities are large enough to escape the Earth. Our study provides an extra assurance that MBHs which might be produced at the LHC are not dangerous.
