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.
