Intersecting domain walls in MQCD

TL;DR

This paper explores the realization of intersecting domain walls in MQCD through Cayley calibrations of M5-branes, discussing dual descriptions and implications for N=1 supersymmetric theories in three dimensions.

Contribution

It introduces a novel geometric interpretation of intersecting domain walls in MQCD using Cayley calibrations and analyzes their dual realizations.

Findings

Intersecting domain walls can be modeled as Cayley calibrations of M5-branes.

Dual descriptions of these domain walls are discussed.

Implications for brane realizations in N=1 supersymmetric theories in D=3.

Abstract

We argue that MQCD admits intersecting domain walls that are realized as Cayley calibrations of the MQCD M5-brane. We discuss various dual realizations and comment on how branes can realise domain walls in N=1 supersymmetric theories in D=3.
