Description
Correlation functions of local gauge-invariant operators are natural
observables inany conformal quantum field theory.
In N=4 SYM a particular role is played by the multipoint supercorrelators
of thestress-tensor multiplet.
Their chiral truncation in the light-cone limit coincides with the scattering
superamplitudes.
We propose a novel approach to calculating such correlators based on the
Lorentz-harmonic superspace.
This technique enables us to obtain the integrands of all such
supercorrelators,including the non-chiral sector, at any loop order.
