We argue that the scattering amplitudes in the maximally supersymmetric N = 4 super-Yang-Mills theory possess a new symmetry which extends the previously discovered dual confor-mal symmetry. Toâ€¦ (More)

We present the analysis of all possible shortenings which occur for composite gauge invariant conformal primary superfields in SU (2, 2/N) invariant gauge theories. These primaries have top-spinâ€¦ (More)

Planar gluon amplitudes in N = 4 SYM are remarkably similar to expectation values of Wilson loops made of light-like segments. We argue that the latter can be determined by making use of theâ€¦ (More)

There is growing evidence that on-shell gluon scattering amplitudes in planar N = 4 SYM theory are equivalent to Wilson loops evaluated over contours consisting of straight, light-like segmentsâ€¦ (More)

We study four-point correlation functions of 12 -BPS operators in N = 4 SYM which are dual to massive KK modes in AdS5 supergravity. On the field theory side, the procedure of inserting the SYMâ€¦ (More)

We develop a manifestly supersymmetric version of the generalized unitarity cut method for calculating scattering amplitudes in N = 4 SYM theory. We illustrate the power of this method by computingâ€¦ (More)

We consider a non-anticommutative N = 2 superspace with an SU(2) singlet and Lorentz scalar deformation parameter, {Î¸ Î±i , Î¸ Î²j } â‹† = âˆ’2iP Ç« Î±Î² Ç« ij. We exploit this unique feature of the N = 2 caseâ€¦ (More)

We compare the two-loop corrections to the finite part of the light-like hexagon Wilson loop with the recent numerical results for the finite part of the MHV six-gluon amplitude in N = 4 SYM theoryâ€¦ (More)

We develop a general setting for N = 2 rigid supersymmetric field theories with gauged central charge in harmonic superspace. We consider those N = 2 multiplets which have a finite number ofâ€¦ (More)

We show that, although the correlator of four stress-tensor multiplets in N = 4 SYM is known to have radiative corrections, certain linear combinations of its components are protected fromâ€¦ (More)
