Pure spinor formalism as an N=2 topological string
(Int School Advanced Studies, 2005-10-01)
Following suggestions of Nekrasov and Siegel, a non-minimal set of fields are added to the pure spinor formalism for the superstring. Twisted (c) over cap = 3 N = 2 generators are then constructed where the pure spinor ...
Pure spinor formalism as an N ≤ 2 topological string
(2005-10-01)
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 pure spinor BRST operator ...

Covariant map between Ramond-Neveu-Schwarz and pure spinor formalisms for the superstring
(Springer, 2014-04-04)
A covariant map between the Ramond-Neveu-Schwarz (RNS) and pure spinor formalisms for the superstring is found which transforms the RNS and pure spinor BRST operators into each other. The key ingredient is a dynamical ...

Dynamical twisting and the b ghost in the pure spinor formalism
(2013-07-26)
After adding an RNS-like fermionic vector ψ m to the pure spinor formalism, the non-minimal b ghost takes a simple form similar to the pure spinor BRST operator. The N=2 superconformal field theory generated by the b ghost ...
