GGI Lectures on the Pure Spinor Formalism of the Superstring
Oscar A. Bedoya, Nathan Berkovits
Notes taken by Oscar A. Bedoya of lectures of Nathan Berkovits in June 2009 at the Galileo Galilei Institute School "New Perspectives in String Theory". Topics include the pure spi…
Ten-Dimensional Super-Twistors and Super-Yang-Mills
Nathan Berkovits
Four-dimensional super-twistors provide a compact covariant description of on-shell N=4 d=4 super-Yang-Mills. In this paper, ten-dimensional super-twistors are introduced which sim…
Non-renormalization conditions for four-gluon scattering in supersymmetric string and field theory
Nathan Berkovits, Michael B. Green, Jorge G. Russo +1
The constraints imposed by maximal supersymmetry on multi-loop contributions to the scattering of four open superstrings in the U(N) theory are examined by use of the pure spinor f…
Decoupling of unphysical states in the minimal pure spinor formalism II
Nathan Berkovits, Joost Hoogeveen, Kostas Skenderis
This is the second of a series of two papers where decoupling of unphysical states in the minimal pure spinor formalism is investigated. The multi-loop amplitude prescription for t…
Pure Spinor Vertex Operators in Siegel Gauge and Loop Amplitude Regularization
Yuri Aisaka, Nathan Berkovits
Since the b ghost in the pure spinor formalism is a composite operator depending on non-minimal variables, it is not trivial to impose the Siegel gauge condition b_0 V=0 on BRST-in…
Regularizing Cubic Open Neveu-Schwarz String Field Theory
Nathan Berkovits, Warren Siegel
After introducing non-minimal variables, the midpoint insertion of Y\bar Y in cubic open Neveu-Schwarz string field theory can be replaced with an operator N_ρdepending on a consta…
