Graviton particle statistics and coherent states from classical scattering amplitudes
Ruth Britto, Riccardo Gonzo, Guy R. Jehu
In the two-body scattering problem in general relativity, we study the final graviton particle distribution using a perturbative approach. We compute the mean, the variance and the…
Proving the dimension-shift conjecture
Ruth Britto, Guy R. Jehu, Andrea Orta
We prove the conjecture made by Bern, Dixon, Dunbar, and Kosower that describes a simple dimension shifting relationship between the one-loop structure of N = 4 MHV amplitudes and…
The dimension-shift conjecture for one-loop amplitudes
Ruth Britto, Guy R. Jehu, Andrea Orta
A conjecture made by Bern, Dixon, Dunbar, and Kosower asserts a simple dimension-shifting relationship between the one-loop structure of N = 4 MHV amplitudes and all-plus helicity…
Symmetric reduction of high-multiplicity one-loop integrals and maximal cuts
Guy R. Jehu
We derive useful reduction formulae which express one-loop Feynman integrals with a large number of external momenta in terms of lower-point integrals carrying easily derivable kin…
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…
Two-Loop Gravity amplitudes from four dimensional Unitarity
David C. Dunbar, Guy R. Jehu, Warren B. Perkins
We compute the polylogarithmic parts of the two-loop four and five-graviton amplitudes where the external helicities are positive and express these in a simple compact analytic for…
The two-loop n-point all-plus helicity amplitude
David C. Dunbar, Guy R. Jehu, Warren B. Perkins
We propose a compact analytic expression for the polylogarithmic part of the n-point two-loop all-plus helicity amplitude in gauge theory.
