Dilepton production at SIS energies
Abstract
In this short review the results of detailed studies for dilepton production from and reactions at SIS energies are presented. The calculations are based on a semi-classical BUU transport model that includes the off-shell propagation of vector mesons and evaluates the width of the vector mesons dynamically. Different scenarios of in-medium modifications of vector mesons, such as collisional broadening and dropping vector meson masses, are investigated and the possibilities for an experimental observation of in-medium effects in reactions at 1--4 GeV are discussed for a variety of nuclear targets.
