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 ...

Topological string on OSP(1|2)/U(1)
(Springer, 2009-12)
We propose an equivalence between topological string on OSP(1|2)/U(1) and Ĉ ≥ 1 superstring with = 1 world-sheet supersymmetry. We examine this by employing a free field representation of OSP(1|2) WZNW model and find an ...

Conformal supergravity in twistor-string theory
(2004-08-01)
Conformal supergravity arises in presently known formulations of twistor-string theory either via closed strings or via gauge-singlet open strings. We explore this sector of twistor-string theory, relating the relevant ...
