Abstract

We present a novel family of Yang-Mills solutions, with gauge group SO(1,3), on Minkowski space that are geometrically distinguished into two classes, viz. interior and exterior of the lightcone. We achieve this by foliating the former with SO(1,3)/SO(3) cosets and the latter with SO(1,3)/SO(1,2) cosets and analytically solving the Yang-Mills equation of an SO(1,3)-invariant gauge field. The resulting fields and their stress-energy tensor, when translated to the Minkowski space, diverge at the lightcone, but we demonstrate how this stress-energy tensor could be regularised due to its unique algebraic structure.

Report

This article is based on a report at the 34th International Colloquium on Group Theoretical Methods in Physics. The author considers the method of constructing analytic solutions of the Yang-Mills equations on the Minkowski space by pulling them back from more easily obtained solutions on the spaces R\times SO(1,3)/H with H=SO(3) or SO(1,2). The technique for constructing such solutions is well known for a long time, the author provides relevant references to the literature and applies the methods developed earlier to the case of non-compact gauge groups used in emergent/modified theories of gravity. The article is written in clear language with all the necessary details. All new solutions are derived carefully and explained in detail. I recommend this article for publication in SciPost Physics Proceedings.

Requested changes

Remarks: I think in Conclusion the author means SO(1,3)/H, not SO(3)/H.
