LOOPS IN SUPER YANG-MILLS THEORIES
Keyword(s):
We report recent analysis of one-loop scattering amplitudes in N =4 super Yang-Mills theories, in the paradigm of maximally helicity violating Feynman diagrams. Non-planar amplitudes are found to be related to planar ones in the same manners as those in conventional field theory. More so, there are are very limited number of loop integrals to be evaluated. For a process with n external particles, there are only [n/2]-1 generically independent integrals.
