Note on I-brane Near Horizon PP-wave Background

TL;DR

This paper constructs a specific PP-wave background with NS flux from intersecting fivebranes in type IIB string theory, finds a related D1-D5 brane solution, and analyzes its supersymmetry features.

Contribution

It introduces a new PP-wave spacetime with NS flux derived from brane intersections and provides a supersymmetry analysis of the associated D1-D5 brane solution.

Findings

Identified a PP-wave background with constant NS flux.

Constructed an intersecting D1-D5 brane solution in this background.

Analyzed supersymmetry properties explicitly.

Abstract

We find out a PP-wave spacetime with constant Neveu-Schwarz (NS) three form flux by taking a Penrose limit on the 1+1 dimensional intersection of two orthogonal stacks of fivebranes in type IIB string theory. We further find out an intersecting (D1-D5)-brane solution in this background and analyze its supersymmetry properties by solving the dilatino and gravitino variations explicitly.
