Open String Spectrum in pp-wave background
نویسنده
چکیده
In this paper, we consider the D-brane, especially D−-brane, in the pp-wave background, which has the eight dynamical and the eight kinematical supercharges. Since the pp-wave background has not a SO(8) but a SO(4)× SO(4) symmetric group, the D-brane world-volume theory has a non-trivial symmetric group which depends on the configuration of D-brane. Here, we will analyze the open string spectrum consistent with the non-trivial symmetric group and, at the low energy limit, classify the field contents of the D-brane world-volume theory which come from the fermionic zero modes of the open string. PACS numbers: 11.25.-w, 11.25.Uv

Tachyon 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 کاملOpen strings in a pp-wave background from defect conformal field theory
Anti–de Sitter strings/conformal field theory ~AdS/CFT! correspondence @1–3# ~for a review, see @4#! has led to deep understandings of string theory and field theory. However, until recently, much of the progress in this direction has been limited to supergravity approximations due to the difficulty when one has a Ramond-Ramond ~RR! background. Recently, it has been shown that string theory can...
متن کاملSuperstrings on PP-Wave Backgrounds and Symmetric Orbifolds
We study the superstring theory on pp-wave background with NSNS-flux that is realized as the Penrose limit of AdS3 × S3 × M4, where M4 is T 4 or T 4/Z2(∼= K3). Quantizing this system in the covariant gauge, we explicitly construct the space-time supersymmetry algebra and the complete set of DDF operators. We analyse the spectrum of physical states by using the spectrally flowed representations ...
متن کاملOpen Strings in PP-Wave Background from Defect Conformal Field Theory
We consider open strings ending on a D5-brane in the pp-wave background, which is realized in the Penrose limit of AdS5×S with an AdS4×S brane. A complete list of gauge invariant operators in the defect conformal field theory is constructed which is dual to the open string states.
متن کاملD-Branes at angle in pp-wave Background
We show the existence of classical solutions of a system of D3-branes oriented at an arbitrary angle with respect to each other, in a six dimensional pp-wave background obtained from AdS3 ×S3 ×R4, with NS−NS and R−R 3-form field strength. These D-brane bound states are shown to preserve 1/16 of the supersymmetries. We also present more D-brane bound state solutions by applying T-duality symmetr...
