Abstract: We present the first results for diquark correlation functions calculated in the Landau gauge on the lattice. Masses have been extracted from the long distance behavior of these correlation functions. We find that the ordering of the diquark masses with spin 0 and 1 states in color anti-triplet and sextet channels is in accordance with instanton motivated interaction models. Although we find evidence for an attractive interaction in color anti-triplet states with a splitting between spin 0 and spin 1 diquarks that can account for the mass splitting between the nucleon and the delta, there is no evidence for a deeply bound diquark state.
