Constructed Dp-Dp' bound state solutions in pp-wave spacetime.

Analyzed supersymmetry properties via Killing spinor equations.

Abstract

We find classical solutions of D-branes in pp-wave spacetime with nonconstant NS-NS flux. We also present Dp-Dp' bound state solutions in this background. We further analyze the supersymmetric properties of these brane solutions by solving the type IIB killing spinor equations explicitly.
