Dp branes in pp-wave background Original Research Article

Dirichlet p-branes in the background of pp-waves are constructed using the massive Green–Schwarz world-sheet action for open strings. These branes are localized at the origin and only for p=7,5,3 preserve half the supersymmetries. The spectrum of the brane theory is analyzed and is found to be in agreement with the spectrum of the small fluctuations of the world-volume super-Yang–Mills theory in this background. These branes are expected to correspond to objects that are nonperturbative in N in the dual gauge theory.
