On-shell recursion in string theory
- Physics
- 2010
We prove that all open string theory disc amplitudes in a flat background obey Britto-Cachazo-Feng-Witten (BCFW) on-shell recursion relations, up to a possible reality condition on a kinematic…

Recursion rules for scattering amplitudes in non-Abelian gauge theories
- Mathematics
- 1997
We present a functional derivation of recursion rules for scattering amplitudes in a non-Abelian gauge theory in a form valid to arbitrary loop order. The tree-level and one-loop recursion rules are…
Light-Cone String Field Theory in a Plane Wave Background
- Physics
- 2003
These lecture notes present an elementary introduction to light-cone string field theory, with an emphasis on its application to the study of string interactions in the plane wave limit of AdS/CFT.…
MHV-vertices for gravity amplitudes
- Physics
- 2005
We obtain a CSW-style formalism for calculating graviton scattering amplitudes and prove its validity through the use of a special type of BCFW-like parameter shift. The procedure is illustrated with…
A direct proof of the CSW rules
- Computer Science
- 2005
Using recursion methods similar to those of Britto, Cachazo, Feng and Witten (BCFW) a direct proof of the CSW rules for computing tree-level gluon amplitudes is given.
Next-to-maximal helicity violating amplitudes in gauge theory
- Physics
- 2005
Using the novel diagrammatic rules recently proposed by Cachazo, Svrcek, and Witten, I give a compact, manifestly Lorentz-invariant form for tree-level gauge-theory amplitudes with three opposite…
MHV vertices and tree amplitudes in gauge theory
- Physics
- 2004
As an alternative to the usual Feynman graphs, tree amplitudes in Yang-Mills theory can be constructed from tree graphs in which the vertices are tree level MHV scattering amplitudes, continued off…
From Yang-Mills lagrangian to MHV diagrams
- Mathematics
- 2006
We prove the equivalence of a recently suggested MHV-formalism to the standard Yang-Mills theory. This is achieved by a formally non-local change of variables. In this note we present the explicit…
