Abstract

We present a calculation of e{sup +}e{sup -} production in gammaA reactions at MAMI and TJNAF energies within a semiclassical Boltzmann-Uehling-Uhlenbeck transport model. Dilepton invariant mass spectra for gamma C, gamma Ca, and gamma Pb are calculated at 0.8, 1.5, and 2.2 GeV. We focus on observable effects of medium modifications of the rho and omega mesons. The in-medium widths of these mesons are taken into account in a dynamical, consistent way. We discuss the transport theoretical treatment of broad resonances.
