Hidden beauty of correlation functions in N=4 SYM

We exhibit a new symmetry of the integrand of the correlation
function of four stress-tensor multiplets in N=4 SYM. It allows us to
predict the integrand up to six loops, without computing Feynman diagrams.
We use these results to derive the anomalous dimension of the Konishi
operator up to five loops, confirming the predictions of the thermodynamic
Bethe Ansatz. We also discuss the relationship between correlation
functions and scattering amplitudes.
