New Supergravity Solutions for Branes in AdS_3 x S^3

TL;DR

This paper presents new explicit supergravity solutions describing 1/2-BPS branes in the AdS_3 x S^3 background, preserving half of the supersymmetry, and consistent with kappa-symmetry, expanding the known spectrum of string theory states.

Contribution

The authors derive explicit supergravity solutions for branes in AdS_3 x S^3 that are new 1/2-BPS states, enhancing the understanding of supersymmetric configurations in this background.

Findings

Solutions preserve 8 of 16 supersymmetries

Solutions are consistent with kappa-symmetry

Represent new 1/2-BPS states in string theory

Abstract

We find explicit supergravity solutions which describe branes in the AdS_3 x S^3 background. These solutions preserve 8 of the 16 supersymmetries of this background, and are consistent with kappa-symmetry. These represent new 1/2-BPS states of string theory.
