Superstrings 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 کاملPP-Wave Holography for Dp-Brane Backgrounds
As an extension of the so-called BMN conjecture, we investigate the plane-wave limit for possible holographic connection between bulk string theories in non-conformal backgrounds of Dp-branes and the corresponding supersymmetric gauge theories for p < 5. Our work is based on the tunneling picture for dominant null trajectories of strings in the limit of large angular momentum. The tunneling nul...
متن کاملComments on D-brane Interactions in PP-wave Backgrounds
We calculate the interaction potential between widely separated D-branes in PP-wave backgrounds in string theory as well as in low-energy supergravity. Timelike and spacelike orientations are qualitatively different but in both cases the effective brane tensions and RR charges take the same values as in Minkowski space in accordance with the expectations from the sigma model perturbation theory.
متن کاملNew Effects in Gauge Theory from pp-wave Superstrings
It has recently been observed that IIB string theory in the pp-wave background can be used to calculate certain quantities, such as the dimensions of BMN operators, as exact functions of the effective coupling λ′ = λ/J. These functions interpolate smoothly between the weak and strong effective coupling regimes of N = 4 SYM theory at large R charge J . In this paper we use the pp-wave superstrin...
متن کاملLinearly-realised Worldsheet Supersymmetry in pp-wave Backgrounds
We study the linearly-realised worldsheet supersymmetries in the “massive” type II lightcone actions for pp-wave backgrounds. The pp-waves have have 16 +Nsup Killing spinors, comprising 16 “standard” Killing spinors that occur in any wave background, plus Nsup “supernumerary” Killing spinors (0 ≤ Nsup ≤ 16) that occur only for special backgrounds. We show that only the supernumerary Killing spi...
