The Many Colours of Amplitudes
Jacob L. Bourjaily, Michael Plesser, Cristian Vergu
We study the colour-dependence of scattering amplitudes in Yang-Mills theory with arbitrary (but fixed) gauge group and various representations of charged matter. When the rank of…
Null Polygonal Wilson Loops in Full N=4 Superspace
Niklas Beisert, Song He, Burkhard U. W. Schwab +1
We compute the one-loop expectation value of light-like polygonal Wilson loops in N=4 super-Yang-Mills theory in full superspace. When projecting to chiral superspace we recover th…
On the Geometry of Null Polygons in Full N=4 Superspace
Niklas Beisert, Cristian Vergu
We discuss various formulations of null polygons in full, non-chiral N=4 superspace in terms of spacetime, spinor and twistor variables. We also note that null polygons are necessa…
The Six-Point NMHV amplitude in Maximally Supersymmetric Yang-Mills Theory
D. A. Kosower, R. Roiban, C. Vergu
We present an integral representation for the parity-even part of the two-loop six-point planar NMHV amplitude in terms of Feynman integrals which have simple transformation proper…
Classical Polylogarithms for Amplitudes and Wilson Loops
Alexander B. Goncharov, Marcus Spradlin, C. Vergu +1
We present a compact analytic formula for the two-loop six-particle MHV remainder function (equivalently, the two-loop light-like hexagon Wilson loop) in N = 4 supersymmetric Yang-…
