Peeking at all orders in N=4 SUSY
The Maldacena conjecture suggests that N=4 gauge theories in the planar
('t Hooft) limit have a special simplicity in the structure of their
perturbative expansions. We demonstrate explicitly that such a simple
relation exists between two-loop and one-loop four-point amplitudes. An
analogous relationship is expected to hold for n-point amplitudes.
Several arguments suggest that a similar structure should continue to
all loop orders.
