Classification of Different Branes at Angles

TL;DR

This paper classifies various D-brane configurations at angles that preserve different fractions of supersymmetry, expanding understanding of brane arrangements in string theory.

Contribution

It introduces a systematic classification of angled D-brane configurations preserving multiple fractions of supersymmetry, including novel configurations with 1/16 SUSY.

Findings

Identified brane configurations preserving 1/2, 1/4, 3/16, 1/8, 1/16 SUSY.

Found configurations with 1/16 SUSY by rotating branes at specific angles.

Provided a framework for analyzing supersymmetry preservation in angled branes.

Abstract

In this paper, we consider two D-branes rotated with respect to each other, and argue that in this way one can find brane configurations preserving ${1 \f 16}$ of SUSY. Also we classify different brane configurations preserving ${1 \f 2}$, ${1 \f 4}$, ${3 \f 16}$,${1 \f 8}$, ${1 \f 16}$ of SUSY.
