Tree Amplitudes in Gauge and Gravity Theories
Abstract
Gauge theory amplitudes in a non-helicity format are generated at all n-point and at tree level. These amplitudes inherit structure from φ3 classical scattering, and the string inspired formalism is used to find the tensor algebra. All of the classical gravity amplitudes are also given. The classical effective action can also be constructed. Generalizations to amplitudes with non spin-1 or 2 is possible.
