Journal ArticleDOI
One-loop n-point gauge theory amplitudes, unitarity and collinear limits
TL;DR: In this article, the authors presented a technique which utilizes unitarity and collinear limits to construct ansatze for one-loop amplitudes in gauge theory, and proved that their N = 4 ansatz is correct.
Journal ArticleDOI
Fusing gauge theory tree amplitudes into loop amplitudes
TL;DR: In this paper, a large class of one-loop amplitudes for massless particles that can be constructed via unitarity from tree amplitudes, without any ambiguities, is identified.
Journal ArticleDOI
One-Loop n-Point Gauge Theory Amplitudes, Unitarity and Collinear Limits
TL;DR: In this paper, the authors presented a technique which utilizes unitarity and collinear limits to construct ansatze for one-loop amplitudes in gauge theory, and proved that their $N=4$ ansatz is correct using general properties of the relevant one-loops $n$-point integrals.
Journal ArticleDOI
On the relationship between Yang-Mills theory and gravity and its implication for ultraviolet divergences
TL;DR: In this paper, an explicit expression for the Ddimensional two-loop contribution to the four-particle S-matrix for N = 8 supergravity was obtained, which was compared to the corresponding N = 4 Yang-Mills result.
Journal ArticleDOI
One-loop self-dual and N = 4 super Yang-Mills
TL;DR: In this paper, the authors conjecture a simple relationship between the one-loop maximally helicity violating gluon amplitudes of ordinary QCD and those of N = 4 supersymmetric Yang-Mills (all but two helicities identical).
