Lepton pair production from photon induced reactions — •E.L. Bratkovskaya, M. Effenberger, and U. Mosel — Institut für Theoretische Physik, Universität Giessen

The dynamical study of e⁺e⁻ production in γ A reactions at MAMI and CEBAF energies has been performed on the basis of the BUU transport approach. Different scenarios of in-medium modifications of vector mesons are investigated. The possibilities for the experimental observation of in-medium effects in γ A reactions are discussed.
