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