BRST Cohomology and Nonlocal Conserved Charges
A relation is found between nonlocal conserved charges in string theory and certain ghost-number two states in the BRST cohomology. This provides a simple proof that the nonlocal conserved charges for the superstring in an AdS 5 × S 5 background are BRST-invariant in the pure spinor formalism and are κ-symmetric in the Green-Schwarz formalism. 1. Introduction Maldacena's conjecture that d = 4 N...
متن کاملOn the NSR formulation of String Theory on AdS5 × S
We discuss the NSR formulation of the superstring action on AdS5 × S proposed recently by Kallosh and Tseytlin in the Green-Schwarz formalism.We show that the stressenergy tensor corresponding to the NSR action for AdS superstring contains the branelike terms, corresponding to exotic massless vertex operators (refered to as the branelike vertices)the 5-form eψm1...ψm5 and the 3-form ∂(e ψm1 ..ψ...
متن کاملVertex operators for AdS3 background with Ramond-Ramond flux
In order to study vertex operators for the Type IIB superstring on AdS space, we derive supersymmetric constraint equations for the vertex operators in AdS3 × S backgrounds with Ramond-Ramond flux, using Berkovits-Vafa-Witten variables. These constraints are solved to compute the vertex operators and show that they satisfy the linearized D = 6, N = (2, 0) equations of motion for a supergravity ...
متن کاملOne Loop Conformal Invariance of the Superstring in an AdS 5 × S 5 Background
It is proven that the pure spinor superstring in an AdS 5 × S 5 background remains conformally invariant at one loop level in the sigma model perturbation theory.
متن کاملQuantum Consistency of the Superstring in AdS 5 × S 5 Background
Using arguments based on BRST cohomology, the pure spinor formalism for the su-perstring in an AdS 5 × S 5 background is proven to be BRST invariant and conformally invariant at the quantum level to all orders in perturbation theory. Cohomology arguments are also used to prove the existence of an infinite set of non-local BRST-invariant charges at the quantum level.
