Relating the Green-Schwarz and Pure Spinor Formalisms for the Superstring
Nathan Berkovits, Dafni Z. Marchioro
Although it is not known how to covariantly quantize the Green-Schwarz (GS) superstring, there exists a semi-light-cone gauge choice in which the GS superstring can be quantized in…
Quantum Consistency of the Superstring in AdS_5 x S^5 Background
Nathan Berkovits
Using arguments based on BRST cohomology, the pure spinor formalism for the superstring in an AdS_5 x S^5 background is proven to be BRST invariant and conformally invariant at the…
Covariant Multiloop Superstring Amplitudes
Nathan Berkovits
In these proceedings, the multiloop amplitude prescription using the super-Poincare invariant pure spinor formalism for the superstring is reviewed. Unlike the RNS prescription, th…
BRST Cohomology and Nonlocal Conserved Charges
Nathan Berkovits
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 c…
WZW-like Action for Heterotic String Field Theory
Nathan Berkovits, Yuji Okawa, Barton Zwiebach
We complete the construction of the Neveu-Schwarz sector of heterotic string field theory begun in hep-th/0406212 by giving a closed-form expression for the action and gauge transf…
Higher-Dimensional Twistor Transforms using Pure Spinors
Nathan Berkovits, Sergey A. Cherkis
Hughston has shown that projective pure spinors can be used to construct massless solutions in higher dimensions, generalizing the four-dimensional twistor transform of Penrose. In…
