D-Branes in Field Theory

TL;DR

This paper develops an open-string description of D-brane solitons in four-dimensional gauge theories, showing that their dynamics are governed by a Chern-Simons-Higgs theory that captures classical scattering at the quantum level.

Contribution

It introduces a novel open-string framework for understanding D-brane solitons in gauge theories, linking classical and quantum descriptions.

Findings

Dynamics governed by Chern-Simons-Higgs theory

Quantum level captures classical scattering

Provides a new open-string perspective

Abstract

Certain gauge theories in four dimensions are known to admit semi-classical D-brane solitons. These are domain walls on which vortex flux tubes may end. The purpose of this paper is to develop an open-string description of these D-branes. The dynamics of the domain walls is shown to be governed by a Chern-Simons-Higgs theory which, at the quantum level, captures the classical "closed string" scattering of domain wall solitons.
