Abstract
Dilepton spectra for p+p and p+d reactions at 4.9 GeV are calculated. We consider electromagnetic bremsstrahlung also in inealstic reactions. N* and {Delta}* decays present the major contributions to the q and {omega} meson yields. Pion annihilation yields only {approx}1.5% of all {rho}`s in p+d. The {rho} mass spectrum is strongly distorted due to phase space effects, populating dominantly dilepton masses below 770 MeV. It is found that inclusive production cross sections of {rho}, {omega} and {eta} mesons in p+p are 3-4 times higher than the (measured) exclusive cross sections for pp+meson. This prediction could be checked by measuring the decays of {rho}, {omega} and {eta} mesons into photons. (orig.)
