Superstrings and D-branes in Plane Wave

Abstract

We carefully analyze the supersymmetry algebra of closed strings and open strings in a plane wave. We use eight component chiral spinors, SO(8) Majorana-Weyl spinors, in lightcone gauge to provide a useful basis of string field theory calculation in the plane wave. We consider the two classes of half BPS D-branes, D±-branes, preserving 16 supersymmetries. We exhaustively provide the supersymmetry algebra of the half BPS branes. We also point out that the supersymmetry algebra distinguishes the two SO(4) directions with opposite sign which is consistent with the Z2 symmetry of the string action.
