Query: Realistic Interactions and Dilepton production off pp-collisions   We present a model for dilepton production of proton-proton collisions using
a realist T-matrix that by incorporating Delta-isobar degrees of freedom fits
the NN-scattering data up to 2 GeV. The results we find differ in details from
earlier work that use less sophisticated interactions but the overall agreement
with these calculations is good.
