Contribution

It introduces a novel approach to construct M5-brane theories from intersecting D3-branes and analyzes the role of tensionless strings and anomalies.

Findings

Constructs M5-brane theories from D3-brane configurations

Analyzes the potential 't Hooft anomaly due to tensionless strings

Provides a framework for understanding intersecting brane dynamics

Abstract

The defect conformal field theory describing intersecting D3-branes at a C^2/Z_k orbifold is used to (de)construct the theory of intersecting M5-branes, as well as M5-branes wrapping the holomorphic curve xy=c. The possibility of a 't Hooft anomaly due to tensionless strings at the intersection is discussed. This note is based on a talk given by Zachary Guralnik at the 35th International Symposium Ahrenshoop on the Theory of Elementary Particles.
