Color Dressed Unitarity and Recursion for Yang-Mills Two-Loop All-Plus Amplitudes
David C. Dunbar, John H. Godwin, Warren B. Perkins +1
We present a direct computation of the full color two-loop five-point all-plus Yang-Mills amplitude using four dimensional unitarity and recursion. We present the amplitu…
Analytic results for two-loop Yang-Mills
David C. Dunbar, John H Godwin, Guy R. Jehu +1
Recent Developments in computing very specific helicity amplitudes in two loop QCD are presented. The techniques focus upon the singular structure of the amplitude rather than on a…
Loop Amplitudes in an Extended Gravity Theory
David C. Dunbar, John H. Godwin, Guy R. Jehu +1
We extend the -matrix of gravity by the addition of the minimal three-point amplitude or equivalently adding terms to the Lagrangian. We demonstrate how Unitarity can be u…
Analytic all-plus-helicity gluon amplitudes in QCD
David C. Dunbar, John H. Godwin, Guy R. Jehu +1
We detail the calculation of two-loop all-plus helicity amplitudes for pure Yang-Mills theory. The four dimensional unitarity methods and augmented recursion techniques we have dev…
Diagrammar in an Extended Theory of Gravity
David C. Dunbar, John H. Godwin, Guy R. Jehu +1
We show how the -matrix of an extended theory of gravity defined by its three-point amplitudes can be constructed by demanding factorisation. The resultant -matrix has tree a…
