Conformal Anomaly for Amplitudes in N=6 Superconformal Chern-Simons Theory
Till Bargheer, Niklas Beisert, Florian Loebbert +1
Scattering amplitudes in three-dimensional N=6 Chern-Simons theory are shown to be non-invariant with respect to the free representation of the osp(6|4) symmetry generators. At tre…
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…
