    "abstract": "The pi omega rho coupling constant is calculated in a relativistic hadronic\nframework incorporating nucleons and Delta(1232) isobars. Medium modifications\nare included. The vertex is analyzed in context of the omega to pi e+e- and rho\nto pi e+e- Dalitz decays in nuclear matter. A sizeable increase of the widths\nfor these decays is found for invariant mass of dileptons in the range 0.2-0.5\nGeV. This increase may help, among other medium effects, to explain the problem\nof the low-mass dilepton enhancement seen in relativistic heavy-ion collisions.",
