Closed Strings in Ramond-Ramond Backgrounds

چکیده
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 worldsheet theory. The results are particularly useful in exploring integrable string dynamics in the context of the holographic duality.

Strings 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 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 کاملD-branes on Orbifolds with Discrete Torsion And Topological Obstruction
We find the orbifold analog of the topological relation recently found by Freed and Witten which restricts the allowed D-brane configurations of Type II vacua with a topologically non-trivial flat B-field. The result relies in Douglas proposal – which we derive from worldsheet consistency conditions – of embedding projective representations on open string Chan-Paton factors when considering orb...
متن کاملCoupling the Superstring to a D-Brane Ramond-Ramond Background
A new approach to couple the type II superstring to the Ramond-Ramond background of D-branes is proposed. Its construction, using the Ramond-Neveu-Schwarz formalism, is based on the unbroken translations of flat D-branes. It is substantiated by a relation between strings in Ramond-Ramond states and the transversally polarized open strings of the D-branes.
متن کاملA study of open strings ending on giant gravitons, spin chains and integrability
We systematically study the spectrum of open strings attached to half BPS giant gravitons in the N = 4 SYM AdS/CFT setup. We find that some null trajectories along the giant graviton are actually null geodesics of AdS5×S, so that we can study the problem in a plane wave limit setup. We also find the description of these states at weak ’t Hooft coupling in the dual CFT. We show how the dual desc...
