Description
I will review some recent (and less recent) results on the calculation of form factors in N=4 super Yang-Mills. Surprisingly, some of these form factors are intimately connected to certain QCD amplitudes describing Higgs + multi gluon processes (without any supersymmetry). After describing this connection, I will discuss the calculation of form factors of protected and non-protected operators in N=4 super Yang-Mills. A notion a universality seems to emerge in the results that will be described. I will comment on this as well as on possible further connections to processes in QCD involving the Higgs boson.
