D-branes from Pure Spinor Superstring in AdS_5 x S^5 Background

TL;DR

This paper classifies 1/2 supersymmetric D-branes in AdS_5 x S^5 by analyzing boundary conditions derived from the pure spinor superstring's BRST transformation surface term.

Contribution

It provides a systematic classification of D-brane configurations in AdS_5 x S^5 using pure spinor formalism and BRST boundary conditions.

Findings

Identifies boundary conditions for supersymmetric D-branes

Classifies possible D-brane configurations in AdS_5 x S^5

Links boundary conditions to supersymmetry preservation

Abstract

We examine the surface term for the BRST transformation of the open pure spinor superstring in an AdS_5 x S^5 background. We find that the boundary condition to eliminate the surface term leads to a classification of possible configurations of 1/2 supersymmetric D-branes.
