Minimally helicity violating, maximally simple scalar amplitudes in N = 4 SYM

In planar N = 4 SYM we study a particular class of helicity preserving amplitudes. These are scalar amplitudes whose flavor configuration is chosen in such a way that only a limited number of diagrams is allowed, which exhibit an iterative structure. For such amplitudes we evaluate the tree level an...
