Supersymmetric Brane-Antibrane Systems: Matrix Model Description, Stability and Decoupling Limits

TL;DR

This paper explores higher-dimensional supersymmetric brane-antibrane configurations within matrix models, analyzing their stability, gauge theories, and decoupling limits to noncommutative theories with preserved supersymmetry.

Contribution

Findings

Identified a non-trivial D3–anti-D3 configuration with E·B ≠ 0.

Analyzed decoupling limits leading to noncommutative super-Yang-Mills.

Explored stability and gauge theory descriptions of brane-antibrane systems.

Abstract

After reviewing the supertubes and super brane-antibrane systems in the context of matrix model, we look for more general higher-dimensional configurations. For D3-bar{D3}, we find a non-trivial configuration with E cdot B not equal to 0 and describe the worldvolume gauge theory. We present the string probe of D3-bar{D3} system and study the decoupling limits leading to either noncommutative Super-Yang-Mills or NCOS theories with eight supercharges.
