Instanton Solutions of the Topological A-model Dual to Free Super-Yang-Mills
Nathan Berkovits
A topological A-model constructed from supertwistor variables and a worldsheet U(1) gauge field was recently proposed to describe the superstring at zero radius w…
Topological A-Model for Superstring and the Maldacena Conjecture
Nathan Berkovits
A topological A-model constructed from supertwistor variables is proposed for the superstring. At zero radius, free N=4 d=4 super-Yang-Mills ampl…
Heterotic String Field Theory with Manifest Spacetime Supersymmetry
Nathan Berkovits, Ulisses M. Portugal
Using the hybrid formalism with manifest spacetime supersymmetry, we construct the quadratic term in the heterotic superstring field theory action. As in open superstri…
Equivalence Proof of Pure Spinor and Ramond-Neveu-Schwarz Superstring Amplitudes
Nathan Berkovits
A new manifestly spacetime-supersymmetric prescription for superstring amplitude computations is given using the pure spinor formalism which does not contain subtleties from poles…
4D Chern-Simons and the pure spinor superstring
Nathan Berkovits, Rodrigo S. Pitombo
Four-dimensional Chern-Simons (4DCS) theory is useful for understanding integrable sigma-models and constructing new ones. In this paper, we show how to derive the complete pure sp…
B-RNS-GSS heterotic string in curved backgrounds
Nathan Berkovits, Osvaldo Chandia, Joao Gomide +1
The recently established B-RNS-GSS formalism is extended for the description of the heterotic superstring in curved backgrounds. We propose a generalized action and BRST charge def…
