Renormalization Group and Black Hole Production in Large Extra Dimensions

TL;DR

This paper explores how a non-Gaussian fixed point in quantum gravity could influence black hole production rates in models with large extra dimensions, by incorporating a running gravitational coupling into the calculations.

Contribution

It introduces a novel approach to include the effects of a non-Gaussian fixed point on black hole production cross sections in large extra dimension models.

Findings

Running gravitational coupling modifies black hole production cross section.

Non-Gaussian fixed point impacts ultraviolet behavior of gravity.

Potential implications for collider experiments and quantum gravity theories.

Abstract

It has been suggested that the existence of a non-Gaussian fixed point in general relativity might cure the ultraviolet problems of this theory. Such a fixed point is connected to an effective running of the gravitational coupling. We calculate the effect of the running gravitational coupling on the black hole production cross section in models with large extra dimensions.
