Lectures on Twistor Strings and Perturbative Yang-Mills Theory
Freddy Cachazo, Peter Svrcek
Recently, Witten proposed a topological string theory in twistor space that is dual to a weakly coupled gauge theory. In this lectures we will discuss aspects of the twistor string…
Tree Level Recursion Relations In General Relativity
Freddy Cachazo, Peter Svrcek
Recently, tree-level recursion relations for scattering amplitudes of gluons in Yang-Mills theory have been derived. In this note we propose a generalization of the recursion relat…
Holomorphic Anomaly Of Unitarity Cuts And One-Loop Gauge Theory Amplitudes
Freddy Cachazo
We show how the holomorphic anomaly found in hep-th/0409245 can be used to efficiently compute certain classes of unitarity cuts of one-loop N=4 amplitudes of gluons. These classes…
Notes on supersymmetric Sp(N) theories with an antisymmetric tensor
Freddy Cachazo
We study supersymmetric Sp(N) gauge theories with an antisymmetric tensor and degree n+1 tree level superpotential. The generalized Konishi anomaly equations derived in hep-th/0304…
N=1 and N=2 Geometry from Fluxes
Freddy Cachazo, Cumrun Vafa
We provide a proof of the equivalence of N=1 dynamics obtained by deforming N=2 supersymmetric gauge theories by addition of certain superpotential terms, with that of type IIB sup…
Geometric Transitions and N=1 Quiver Theories
F. Cachazo, S. Katz, C. Vafa
We construct N=1 supersymmetric theories on worldvolumes of D5 branes wrapped around 2-cycles of threefolds which are A-D-E fibrations over a plane. We propose large N duals as geo…
