TL;DR

This paper explores the existence and structure of BPS string webs in six-dimensional (2,0) superconformal theories, revealing their constituents, symmetries, and connections to other supersymmetric theories.

Contribution

It introduces the concept of BPS string webs in 6D (2,0) theories, detailing their constituents and supporting evidence from related lower-dimensional theories and brane configurations.

Findings

Existence of 1/4, 1/8, 1/16 BPS string webs in 6D (2,0) theories

Correlation between spatial and internal SO(5) rotations in these webs

Connections to BPS webs in 5D gauge theories and M-brane configurations

Abstract

In the Coulomb phase of the 6-dim (2,0) superconformal theories, the 1/4, 1/8, 1/16 BPS selfdual string webs are argued to exist such that the spatial SO(5) and internal SO(5) rotations are correlated. The basic constituents are 1/2 BPS strings and 1/4 BPS string junctions. One support comes from the existence of the similar BPS dyonic monostring webs in 5-dim maximally supersymmetric gauge theories. Another comes from the study of the supersymmetry of the intersecting M2 brane stripes terminating on M5 branes. We also discuss the related BPS webs in little string theories and other theories.
