Superstring Perturbation Theory and Ramond-Ramond Backgrounds
We consider perturbative Type II superstring theory in the covariant NSR formalism in the presence of NSNS and RR backgrounds. A concrete example that we have in mind is the geometry of D3-branes which in the near-horizon region is AdS5 × S5, although our methods may be applied to other backgrounds as well. We show how conformal invariance of the string path integral is maintained order by orde...
متن کاملQuantization of the Superstring in Ramond-Ramond Backgrounds
Sigma model actions are constructed for the Type II superstring compactified to four and six dimensional curved backgrounds which can contain non-vanishing Ramond-Ramond fields. These actions are N=2 worldsheet superconformally invariant and can be covariantly quantized preserving manifest spacetime supersymmetry. They are constructed using a hybrid version of superstring variables which combin...
متن کاملStrings in Ramond-Ramond backgrounds
We write the type IIB worldsheet action in classes of bosonic curved backgrounds threaded with Ramond-Ramond fluxes. The fixing of the kappa symmetry in the lightcone gauge and the use of the Bianchi identities of the supergravity theory lead to an expression of a relatively simple form, yet rich with new physical information about how fundamental strings react to the presence of RR fields. The...
متن کاملT-duality in Ramond-Ramond backgrounds
Target space duality is a symmetry of string theory that maps a string theory in a background to a dual string theory in a dual background. For reviews see [1][2]. The map between T-dual backgrounds was derived in a world-sheet path integral formalism for Neveu-Schwarz NeveuSchwarz fields in [3]. For Ramond-Ramond backgrounds in type II, various derivations have appeared in the literature: the ...
متن کاملClosed Strings in Ramond-Ramond Backgrounds
We write the IIB Green-Schwarz action in certain general classes of curved backgrounds threaded with Ramond-Ramond fluxes. The fixing of the kappa symmetry in the light-cone gauge and the use of supergravity Bianchi identities simplify the task. We find an expression that truncates to quartic order in the spacetime spinors and relays interesting information about the vacuum structure of the wor...
