Abstract
We extend hadronic models for rho-meson propagation in cold nuclear ma tter via coupling to in-medium pions to include finite three-momentum. Special care is taken to preserve gauge invariance. Consequences for photoabsorption on the proton and on nuclei as well as for the dilepto n production in relativistic heavy-ion collisions are discussed. (C) 1 998 Elsevier Science B.V.
