Untwisting the pure spinor formalism to the RNS and twistor string in a flat and AdS5 × S 5 background
(2016-06-01)
Abstract: The pure spinor formalism for the superstring can be formulated as a twisted N=2 worldsheet theory with fermionic generators jBRST and composite b ghost. After untwisting the formalism to an N=1 worldsheet theory ...
Notes on beta-deformations of the pure spinor superstring in AdS(5) x S-5
(Elsevier B.V., 2011-07-01)
We study the properties of the vertex operator for the beta-deformation of the superstring in AdS(5) x S-5 in the pure spinor formalism. We discuss the action of supersymmetry on the infinitesimal beta-deformation, the ...

Cornering the unphysical vertex
(Springer, 2012-11-01)
In the classical pure spinor worldsheet theory of AdS(5) x S-5 there are some vertex operators which do not correspond to any physical excitations. We study their flat space limit. We find that the BRST operator of the ...

Constrained BV description of string field theory
(Springer, 2012-03-01)
In the conventional BV description of string field theory, the string field Phi is split as Phi = Psi vertical bar Psi* where Psi includes all states with ghost number <= G and describes the spacetinte fields, and Psi* ...

(ELSEVIER SCIENCE BV, 2011)
We study the properties of the vertex operator for the beta-deformation of the superstring in AdS(5) x S(5) in the pure spinor formalism. We discuss the action of supersymmetry on the infinitesimal beta-deformation, the ...
Towards a worldsheet derivation of the Maldacena conjecture
(American Institute of Physics (AIP), 2008-01-01)
A U(2,2 vertical bar 4)-invariant A-model constructed from fermionic superfields has recently been proposed as a sigma model for the superstring on AdS(5) X S(5). After explaining the relation of this A-model with the pure ...
Bosonic sectorized strings and the (DF)(2) theory
(Springer, 2020-01-15)
In this work, we investigate the bosonic chiral string in the sectorized inter- pretation, computing its spectrum, kinetic action and 3-point amplitudes. As expected, the bosonic ambitwistor string is recovered in the ...
