Dilepton Production in Elementary Processes on the Nucleon

We study elementary processes for production of dileptons from nucleons, either through NN bremsstrahlung or through photon-induced reactions. We emphasize the dependence of the expected cross-sections on the electromagnetic formfactor of the nucleon in the time-like regime and point out that the mentioned reactions can provide important information on the validity of vector meson dominance for the nucleon. We also study the off-shell dependence of the formfactors.
