Abstract

We have performed a detailed study of dilepton production from pp collisions including the subthreshold $\rho$ production via baryonic resonances (N(1520), N(1700)) in addition to the conventional dilepton sources as $\pi^0, \eta, \omega$ and $\Delta$ Dalitz decays and direct decays of vector mesons ( $\rho, \omega$ ). The role of baryonic resonances in $\rho$ production from nucleon-nucleon collisions is studied in comparison to the DLS data which are well described.
