All rational one-loop

All four-point mixed gluon-graviton amplitudes in pure Einstein-Yang-Mills theory with at most one state of negative helicity are computed at one-loop order and maximal powers of the gauge coupling,

Simplifying amplitudes in Maxwell-Einstein and Yang-Mills-Einstein supergravities

Abstract This chapter reviews recent progress in formulating and extending doublecopy constructions for scattering amplitudes in supergravities with eight supercharges (N = 2 supersymmetry) in five

One-loop amplitudes for N = 2 homogeneous supergravities

We compute one-loop matter amplitudes in homogeneous Maxwell-Einstein supergravities with N = 2 supersymmetry using the double-copy construction. We start from amplitudes of N = 2 super-Yang-Mills

Extracting bigravity from string theory

Abstract The origin of the graviton from string theory is well understood: it corresponds to a massless state in closed string spectra, whose low-energy effective action, as extracted from string

The momentum kernel of gauge and gravity theories

We derive an explicit formula for factorizing an n-point closed string amplitude into open string amplitudes. Our results are phrased in terms of a momentum kernel which in the limit of infinite

Calculating scattering amplitudes efficiently

We review techniques for more efficient computation of perturbative scattering amplitudes in gauge theory, in particular tree and one- loop multi-parton amplitudes in QCD. We emphasize the advantages

Scattering of massless particles in arbitrary dimensions.

A compact formula for the complete tree-level S-matrix of pure Yang-Mills and gravity theories in arbitrary spacetime dimensions is presented and Gauge invariance is completely manifest as it follows from a simple property of the Pfaffian.

The nature of the graviton as a bound state in open-string field theory is clarified and the flat metric in the action appears as the vacuum value of an [ital open] string field.

New Relations for Gauge-Theory Amplitudes

We present an identity satisfied by the kinematic factors of diagrams describing the tree amplitudes of massless gauge theories. This identity is a kinematic analog of the Jacobi identity for color
