It is well known in NSR string theory, that vertex operators can be constructed in various ``pictures''. Recently this was discussed in the context of pure spinor formalism. NSR picture changing operators have an elegant super-geometrical interpretation. In this paper we provide a generalization of this super-geometrical construction, which is also applicable to the pure spinor formalism. 
AdS 5 × S5 supergravity vertex operators
Abstract In any type II superstring background, the supergravity vertex operators in the pure spinor formalism are described by a gauge superfield. In this paper, we obtain for the first time anExpand


Conformal invariance, supersymmetry and string theory
Covariant quantization of string theories is developed in the context of conformal field theory and the BRST quantization procedure. The BRST method is used to covariantly quantize superstrings, andExpand
Notes on beta-deformations of the pure spinor superstring in AdS(5) x S-5
We study the properties of the vertex operator for the beta-deformation of the superstring in AdS(5) x S(5) in the pure spinor formalism. We discuss the action of supersymmetry on the infinitesimalExpand
Multiloop superstring amplitudes from non-minimal pure spinor formalism
Using the non-minimal version of the pure spinor formalism, manifestly super-Poincare covariant superstring scattering amplitudes can be computed as in topological string theory without the need ofExpand
Picture changing operators in supergeometry and superstring theory
Geometrical meaning of superstring pictures is discussed in details. An off-shell generalization of the picture changing operation and its inverse are constructed. It is demonstrated that theExpand
Type IIB superstring vertex operator from the -8 picture.
A new procedure was recently proposed for constructing massless Type IIB vertex operators in the pure spinor formalism. Instead of expressing these closed string vertex operators as left-rightExpand
Perturbative super-Yang-Mills from the topological AdS 5 × S 5 sigma model
A topological sigma model based on the pure spinor formalism was recently proposed for the small radius limit of the AdS5 × S5 superstring. Physical states in this model can be constructed byExpand
Super-Chern-Simons Theory as Superstring Theory
Superstrings and topological strings with supermanifolds as target space play a central role in the recent developments in string theory. Nevertheless the rules for higher-genus computations areExpand
New Geometrical Approach to Superstrings
We present a new geometrical approach to superstrings based on the geometrical theory of integration on supermanifolds. This approach provides an effective way to calculate multi-loop superstringExpand
Half-BPS vertex operators of the AdS5 × S5 superstring
A bstractUsing the pure spinor formalism for the superstring in an AdS5 × S5 background, a simple expression is found for half-BPS vertex operators. At large radius, these vertex operators reduce toExpand
Simplifying and Extending the AdS_5xS^5 Pure Spinor Formalism
Although the AdS5 × S5 worldsheet action is not quadratic, some features of the pure spinor formalism are simpler in an AdS5 × S5 background than in a flat background. The BRST operator actsExpand
