Topological Mass Generation in Four Dimensions

TL;DR

This paper explores how topological structures in four-dimensional gauge theories can generate mass, extending Schwinger's mechanism from two to four dimensions.

Contribution

It introduces a novel topological mass generation mechanism in four-dimensional gauge theories based on 4D topological entities.

Findings

Extension of Schwinger's mechanism to four dimensions.

Potential implications for mass generation in quantum field theories.

Abstract

Schwinger's mechanism for mass generation relies on topological structures of a 2-dimensional gauge theory. In the same manner, corresponding 4-dimensional topological entities give rise to topological mass generation in four dimensions.
