Abstract
The scattering amplitude φφ→φ¯φ¯, where φ (φ¯) is a chiral (antichiral) superfield, is computed to one-loop order in the massless version of the finite N=4 super Yang-Mills theory. The leading term of the amplitude describes the scattering of scalar particles. As expected, no ultraviolet divergences appear. There are, however, infrared divergences in the process that do not cancel.
