Superstrings and D-branes in Plane Wave
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 supersymmet...
متن کاملMore D-branes in plane wave spacetime
We present classical solutions of Dp-branes (p ≥ 5) in plane wave spacetime with nonconstant R-R 3-form flux. We also show the existence of a system of D3-branes in this background. We further analyze the supersymmetric properties of these branes by solving type II Killing spinor equations explicitly. e-mail: [email protected] †b Present address (I.N.F.N.

متن کاملTachyon Condensation and Non-BPS D-branes in a Ramond-Ramond Plane Wave Background
We consider string theory in maximally supersymmetric type IIB plane wave background with constant five form Ramond-Ramond flux (RR plane wave). It is argued that there exists a universal sector of string configurations independent of the null coordinate x such that the space-time action evaluated at such a configuration is same in the RR plane wave and flat background. By naturally assuming it...
متن کاملAn overview of branes in the plane wave background
We give an overview of D-branes in the maximally supersymmetric plane wave background of IIB supergravity. We start by reviewing the results of the probe analysis. We then present the open string analysis and show how certain spacetime symmetries are restored using worldsheet symmetries. We discuss the construction of these branes as boundary states and summarize what is known about the dual ga...
متن کاملD-branes in a plane wave from covariant open strings
We derive boundary conditions for the covariant open string corresponding to D-branes in an Hpp-wave, by requiring kappa symmetry of its bulk action. Both half-supersymmetric and quarter-supersymmetric branes are seen to arise in this way, and the analysis furthermore agrees fully with the existing probe brane and supergravity computations. We elaborate on the origin of dynamical and kinematica...
