Superstrings and D-branes in Plane Wave
نویسندگان
چکیده
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.

Superstrings and D-branes in A Plane Wave
We carefully analyze the supersymmetry algebra of closed strings and open strings in a type IIB plane wave background. We use eight component chiral spinors, SO(8) MajoranaWeyl spinors, in light-cone gauge to provide a useful basis of string field theory calculation in the plane wave. We consider the two classes of D-branes, D±-branes, and give a worldsheet derivation of conserved supercurrents...
متن کاملD-branes of Covariant AdS Superstrings
We consider D-branes of open superstrings in the AdS5 × S background. The possible configurations of D-branes preserving half of supersymmetries are classified by analyzing the κ-invariance of an open superstring in a covariant manner. We also revisit the classification of D-branes in the pp-wave background. It is shown that Penrose limits of the possible D-branes in the AdS5 × S give all of th...
متن کاملMore on supersymmetric D-branes in type IIB plane wave background
We extend the study on D-branes in the type IIB plane wave background to less supersymmetric configurations. We show that many new supersymmetric D-branes can be found by turning on electric as well as magnetic background fluxes, or constantly boosting D-branes.
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 کاملThermal D-branes States from Superstrings in Light-Cone Gauge
In this talk we are going to review a method to construct the thermal boundary states of the thermal string in the TFD approach. The class of thermal boundary states presented here is derived from the BPS D-branes of the type II GS superstrings.
