New Critical Behavior in Einstein-Yang-Mills Collapse

TL;DR

This paper discovers a new critical behavior in the gravitational collapse of Yang-Mills fields, revealing a connection to colored black holes and distinguishing different black hole formation processes.

Contribution

It identifies a novel critical behavior in Einstein-Yang-Mills collapse and links it to known colored black hole solutions, expanding understanding of collapse dynamics.

Findings

New critical behavior separates Type I and Type II black hole formation.

Colored black holes serve as critical solutions with a single unstable mode.

Evidence supports the connection between critical solutions and known colored black holes.

Abstract

We extend the investigation of the gravitational collapse of a spherically symmetric Yang-Mills field in Einstein gravity and show that, within the black hole regime, a new kind of critical behavior arises which separates black holes formed via Type I collapse from black holes formed through Type II collapse. Further, we provide evidence that these new attracting critical solutions are in fact the previously discovered colored black holes with a single unstable mode.
