Pure spinor formalism as an N=2 topological string

- N. Berkovits
- Physics
- 15 September 2005

Following suggestions of Nekrasov and Siegel, a non-minimal set of fields are added to the pure spinor formalism for the superstring. Twisted ĉ = 3 N = 2 generators are then constructed where the… Expand

Conformal Field Theory of AdS Background with Ramond-Ramond Flux

- N. Berkovits, C. Vafa, E. Witten
- Physics
- 12 February 1999

We review a formalism of superstring quantization with manifest six-dimensional spacetime supersymmetry, and apply it to AdS3 × S3 backgrounds with Ramond-Ramond flux. The resulting description is a… Expand

Fermionic T-Duality, Dual Superconformal Symmetry, and the Amplitude/Wilson Loop Connection

- N. Berkovits, J. Maldacena
- Physics
- 21 July 2008

We show that tree level superstring theories on certain supersymmetric backgrounds admit a symmetry which we call ``fermionic T-duality''. This is a non-local redefinition of the fermionic worldsheet… Expand

Ten-dimensional supergravity constraints from the pure spinor formalism for the superstring

- N. Berkovits, P. Howe
- Physics
- 18 December 2001

Abstract It has recently been shown that the ten-dimensional superstring can be quantized using the BRST operator Q =∮ λ α d α , where λ α is a pure spinor satisfying λγ m λ =0 and d α is the… Expand

Multiloop amplitudes and vanishing theorems using the pure spinor formalism for the superstring

- N. Berkovits
- Physics
- 5 June 2004

A ten-dimensional super-Poincare covariant formalism for the superstring was recently developed which involves a BRST operator constructed from superspace matter variables and a pure spinor ghost… Expand

Super-Poincaré invariant superstring field theory

- N. Berkovits
- Physics
- 15 March 1995

Abstract Using the topological techniques developed in an earlier paper with Vafa, a field theory action is constructed for any open string with critical N = 2 worldsheet superconformal invariance.… Expand

N = 4 topological strings

- N. Berkovits, C. Vafa
- Physics
- 28 July 1994

Abstract We show how to make a topological string theory starting from an N = 4 superconformal theory. The critical dimension for this theory is c = 2 (c = 6) . It is shown that superstrings (in both… Expand

Multiloop superstring amplitudes from non-minimal pure spinor formalism

- N. Berkovits, N. Nekrasov
- Physics
- 1 September 2006

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 of… Expand
