D-brane Configurations for Domain Walls and Their Webs

TL;DR

This paper explores the realization of supersymmetric domain walls and their webs in gauge theories using D-brane configurations, providing a geometric understanding of these solitons and extending previous work on their brane interpretations.

Contribution

It introduces new brane configurations for domain wall webs in supersymmetric gauge theories, building on prior models and offering insights into their geometric and string theory descriptions.

Findings

Domain walls are realized as kinky fractional D3-branes.

Brane configurations for domain wall webs are constructed.

The work extends previous models to include web structures.

Abstract

Supersymmetric U(Nc) gauge theory with Nf massive hypermultiplets in the fundamental representation admits various BPS solitons like domain walls and their webs. In the first part we show as a review of the previous paper hep-th/0412024 that domain walls are realized as kinky fractional D3-branes interpolating between separated D7-branes. In the second part we discuss brane configurations for domain wall webs. This is a contribution to the conference based on the talk given by MN.
