Superconformal invariance of scattering amplitudes in N=4 super-Yang-Mills theory
 
We discuss the realization of dual and conventional 
superconformal symmetries on the scattering amplitudes in 
N=4 SYM. While these symmetries are exact at tree level, 
they have to be complemented with analytic properties to 
fully fix the tree. At loop level both symmetries are broken 
by different mechanisms. We describe the formulation of 
amplitudes in twistor space and in terms of Grassmannian 
invariants.
