Branes at angles and calibrated geometry

TL;DR

This paper extends the analysis of supersymmetric intersecting branes to multiple M5 and M2-branes using calibrated geometry, providing a broader understanding of their geometric and physical configurations.

Contribution

It generalizes previous results on intersecting M-branes by applying calibrated geometry to multiple branes, offering new insights into supersymmetric configurations.

Findings

Extended supersymmetry conditions to multiple M-branes.

Linked brane configurations to calibrated geometric structures.

Provided a geometric framework for analyzing intersecting branes.

Abstract

In a recent paper, Ohta and Townsend studied the conditions which must be satisfied for a configuration of two intersecting M5-branes at angles to be supersymmetric. In this paper we extend this result to any number of M5-branes or any number of M2-branes. This is accomplished by interpreting their results in terms of calibrated geometry, which is of independent interest.
