Massive superstring vertex operator in D = 10 superspace
(2002-08-01)
Using the pure spinor formalism for the superstring, the vertex operator for the first massive states of the open superstring is constructed in a manifestly super-Poincaré covariant manner. This vertex operator describes ...
The Ramond sector of open superstring field theory
(2001-12-01)
Although the equations of motion for the Neveu-Schwarz (NS) and Ramond (R) sectors of open superstring field theory can be covariantly expressed in terms of one NS and one R string field, picture-changing problems prevent ...
Multiloop amplitudes and vanishing theorems using the pure spinor formalism for the superstring
(2004-09-01)
A ten-dimensional super-Poincaré covariant formalism for the superstring was recently developed which involves a BRST operator constructed from superspace matter variables and a pure spinor ghost variable. A super-Poincaré ...
Infinite tension limit of the pure spinor superstring
(2014-03-01)
Mason and Skinner recently constructed a chiral infinite tension limit of the Ramond-Neveu-Schwarz superstring which was shown to compute the Cachazo-He-Yuan formulae for tree-level d = 10 Yang-Mills amplitudes and the ...
Exploring the lambda model of the hybrid superstring
(2016-10-01)
The purpose of this contribution is to initiate the study of integrable deformations for different superstring theory formalisms that manifest the property of (classical) integrability. In this paper we choose the hybrid ...
Light-cone analysis of the pure spinor formalism for the superstring
(Springer, 2014-08-18)
Physical states of the superstring can be described in light-cone gauge by acting with transverse bosonic alpha(j)(-n) and fermionic q(-n)(-a) operators on an SO(8)-ovariant superfield where j,a = 1 to 8. In the pure spinor ...
Super-Poincaré covariant quantization of the superstring
(2000-12-01)
Using pure spinors, the superstring is covariantly quantized. For the first time, massless vertex operators are constructed and scattering amplitudes are computed in a manifestly ten-dimensional super-Poincaré covariant ...
Infinite tension limit of the pure spinor superstring
(Springer, 2014-03-04)
Mason and Skinner recently constructed a chiral infinite tension limit of the Ramond-Neveu-Schwarz superstring which was shown to compute the Cachazo-He-Yuan formulae for tree-level d=10 Yang-Mills amplitudes and the NS-NS ...
Flat currents in the classical AdS5 × S5 pure spinor superstring
(2004-03-01)
It is proven that the classical pure spinor superstring in an AdS 5 × S5 back-ground has a flat current depending on a continuous parameter. This generalizes the recent result of Bena, et al. for the classical Green-Schwarz ...
The Ramond sector of open superstring field theory
(2001-12-01)
Although the equations of motion for the Neveu-Schwarz (NS) and Ramond (R) sectors of open superstring field theory can be covariantly expressed in terms of one NS and one R string field, picture-changing problems prevent ...
