Supersymmetric defects in the Maldacena-Nunez background

TL;DR

This paper identifies supersymmetric D5-brane configurations in the Maldacena-Nunez background that act as defects in the gauge theory, preserving some supersymmetry and extending along specific spatial directions.

Contribution

It provides explicit supersymmetric D5-brane embeddings acting as defects in the Maldacena-Nunez background, preserving partial supersymmetry.

Findings

Constructed codimension one and two defect configurations.

These embeddings preserve two of four background supersymmetries.

The configurations behave as worldvolume solitons.

Abstract

We find supersymmmetric configurations of a D5-brane probe in the Maldacena-Nunez background which are extended along one or two of the spatial directions of the gauge theory. These embeddings are worldvolume solitons which behave as codimension two or one defects in the gauge theory and preserve two of the four supersymmetries of the background.
