    "abstract": "We present consistent theoretical descriptions of the $\\pi N \\to e^+e^- N$\nand $\\gamma N \\to e^+e^- N$ reactions on proton and neutron targets for total\ncenter of mass energies $\\sqrt s$ ranging between 1.50 GeV and 1.75 GeV. These\nreactions are complementary to study the coupling of low-lying baryon\nresonances to vector meson-nucleon channels. We show in particular how the\nresonant structure of the amplitudes for both processes generates specific and\nlarge quantum interferences between $\\rho$- and $\\omega$-meson decays into\n$e^+e^-$ pairs. Data on the $\\pi N \\to e^+e^- N$ and $\\gamma N \\to e^+e^- N$\nreactions are expected in the near future from the HADES program at GSI and\nfrom dilepton studies with CLAS at JLab.",
