YangMills ChernSimons Corrections From The Pure Spinor Superstring
, 2008
"... Nilpotency of the pure spinor BRST operator in a curved background implies superspace equations of motion for the background. By computing oneloop corrections to nilpotency for the heterotic sigma model, the YangMills ChernSimons corrections to the background are derived. ..."

Nilpotency of the pure spinor BRST operator in a curved background implies superspace equations of motion for the background. By computing oneloop corrections to nilpotency for the heterotic sigma model, the YangMills ChernSimons corrections to the background are derived.
Character of pure spinors
"... The character of holomorphic functions on the space of pure spinors in ten, eleven and twelve dimensions is calculated. From this character formula, we derive in a manifestly covariant way various central charges which appear in the pure spinor formalism for the superstring. We also derive in a simp ..."

Pure Spinor Formalism as an N=2 Topological String
, 2005
"... Following suggestions of Nekrasov and Siegel, a nonminimal 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 is the fermionic spinone generator, and the formalism is interpreted as a criti ..."

(Non)triviality of Pure Spinors and Exact Pure Spinor RNS Map
, 2008
"... All the BRSTinvariant operators in pure spinor formalism in d = 10 can be represented as BRST commutators, such as V = {Qbrst, θ+ λ+ V} where λ+ is the U(5) component of the pure spinor transforming as 1 5. Therefore, in order to secure nontriviality of BRST 2 cohomology in pure spinor string theo ..."

Ten–dimensional supergravity constraints from the pure spinor formalism for the superstring,” Nucl. Phys. B635
, 2002
"... It has recently been shown that the tendimensional superstring can be quantized using the BRST operator Q = ∮ λ α dα where λ α is a pure spinor satisfying λγ m λ = 0 and dα is the fermionic supersymmetric derivative. In this paper, the pure spinor version of superstring theory is formulated in a c ..."

On the BRST Cohomology of Superstrings with/without Pure Spinors
, 2002
"... We replace our earlier condition that physical states of the superstring have nonnegative grading by the requirement that they are analytic in a new real commuting constant t which we associate with the central charge of the underlying KacMoody superalgebra. The analogy with the twisted N=2 SYM th ..."

theory suggests that our covariant superstring is a twisted version of another formulation with an equivariant cohomology. We prove that our vertex operators correspond in onetoone fashion to the vertex operators in Berkovits’ approach based on pure spinors. Also the zeromomentum cohomology is equal

BRST quantization of the pure spinor superstring
, 2007
"... We present a derivation of the scattering amplitude prescription for the pure spinor superstring from first principles, both in the minimal and nonminimal formulations, and show that they are equivalent. This is achieved by first coupling the worldsheet action to topological gravity and then procee ..."

Compactification of the Heterotic Pure Spinor

"... In this paper we begin the study of compactifications of the pure spinor formalism for superstrings. As a first example of such a process we study the case of the heterotic string in a CalabiYau background. We explicitly construct a BRST operator imposing N = 1 fourdimensional supersymmetry and sh ..."

New BRST Charges in RNS Superstring Theory and Deformed Pure Spinors

"... We show that new BRST charges in RNS superstring theory with nonstandard ghost numbers, constructed in our recent work, can be mapped to deformed pure spinor (PS) superstring theories, with the nilpotent pure spinor BRST charge QPS = ∮ λ α dα still retaining its form but with singular operator prod ..."
