  Title C Ambitwistor pure spinor string in a type II supergravity background Type
  Year 2015 Publication Journal Of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume Issue 6 Pages 15 pp  
  Keywords Superstrings and Heterotic Strings; Supergravity Models  
  Abstract We construct the ambitwistor pure spinor string in a general type II supergravity background in the semi-classical regime. Almost all supergravity constraints are obtained from nilpotency of the BRST charge and further consistency conditions from additional world-sheet the case of AdS(5) x S (5) background.

  Title Non-minimal fields of the pure spinor string in general curved backgrounds Type
  Year 2015 Publication Journal Of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume Issue 2 Pages 16 pp  
  Keywords Superstrings and Heterotic Strings; Conformal Field Models in String Theory  
  Abstract We study the coupling of the non-minimal ghost fields of the pure spinor superstring in general curved backgrounds. The coupling is found solving the consistency relations from the nilpotency of the non-minimal BRST charge.

  Year 2014 Publication Journal Of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume Issue 6 Pages 16 pp  
  Keywords Superstrings and Heterotic Strings; Conformal Field Models in String Theory; BRST Symmetry  
  Abstract In this paper we study the pure spinor formulation of the superstring in AdS(5) x S-5 around point particle solutions of the classical equations of motion. As a particular example we quantize the pure spinor string in the BMN background.

  Title Compactification of the heterotic pure spinor superstring II Type
  Year 2011 Publication Journal Of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume Issue 10 Pages 22 pp  
  Keywords Superstrings and Heterotic Strings; Superstring Vacua  
  Abstract We study compactifications of the heterotic pure spinor superstring to six and four dimensions focusing on two simple Calabi-Yau orbifolds. We show that the correct spectrum can be reproduced only if, in the twisted sector, there remain exactly 5 and 2 pure spinor components untwisted, respectively. This naturally defines a “small” Hilbert space of untwisted variables. We point out that the cohomology of the reduced differential on this small Hilbert space can be used to describe the states in the untwisted sector, provided certain auxiliary constraints are defined. In dimension six, the mismatch between the number of pure spinor components in the small Hilbert space and the number of components of a six-dimensional pure spinor is interpreted as providing the projective measure on the analytic subspace (in the projective description) of harmonic superspace.

  Title A construction of integrated vertex operator in the pure spinor sigma-model in AdS(5) x S-5 Type
  Year 2013 Publication Journal Of High Energy Physics Abbreviated Journal J. High Energy Phys.  
  Volume 2013 Issue 11 Pages 11 pp  
  Keywords Superspaces; NoN-Commutative Geometry; Conformal Field Models in String Theory; AdS-CFT Correspondence  
  Abstract Vertex operators in string theory me in two varieties: integrated and unintegrated. Understanding both types is important for the calculation of the string theory amplitudes. The relation between them is a descent procedure typically involving the b-ghost. In the pure spinor formalism vertex operators can be identified as cohomology classes of an infinite-dimensional Lie superalgebra formed by covariant derivatives. We show that in this language the construction of the integrated vertex from an unintegrated vertex is very straightforward, and amounts to the evaluation of the cocycle on the generalized Lax currents.
