Closed 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...
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 کاملStrings in Nontrivial Gravitino and Ramond-ramond Backgrounds
In this paper we discuss deformations of the BRST operator of the fermionic string. These deformations preserve inlpotency of the BRST operator and correspond to turning on infinitesimal Gravitino and Ramond-Ramond spacetime fields. [email protected] One of the outstanding problems of string theory is to understand the equations of motion for the fields of the theory ( massless and...
متن کاملOn the Polarization of Closed Strings by Ramond-Ramond Fluxes
In the Green-Schwarz formalism, the closed string worldsheet of the IIB theory couples to Ramond-Ramond (RR) fluxes through spinor bilinears. We study the effect of such fluxes by analyzing the supersymmetry transformation of the worldsheet in general backgrounds. We show that, in the presence RR fields, the closed string can get ‘polarized’, as the spinors acquire non-zero vevs in directions c...
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 ...
