The properties of vector mesons in nuclear matter are discussed. Results for the momentum dependence of the ρ-meson self energy in matter due to ρN interactions are presented, and consequences for the production rate of e+e− pairs in hot and dense matter are discussed. I also examine the constraints imposed by elementary processes on the widths of ρ and ω mesons in nuclear matter, and conclude ...

We calculate the in-medium D meson self-energies in a hot pion gas induced by resonance interactions with pions. The appropriate resonances in the s, p and d waves of the D meson-pion pair are represented by low lying scalar, vector and tensor D∗ mesons. At temperatures around 200 MeV the D-meson mass drops by 30 MeV and the scattering width grows up to 60 MeV. Similar medium effects are found ...

This document gives a detailed account of the terms used in the computation of the ground state mean field and the ground state correlations. While the general approach to this description is given in a separate paper (nucl-th/9802029) we give here the explicite expressions used. PACS: 21.60.−n, 21.60.Gx, 21.60.Cs, 21.60.Jz

The effective intercept parameter of the two-pion Bose-Einstein Correlation function, λ * , is found to be sensitive to partial restoration of U A (1) symmetry in ultra-relativistic nuclear collisions. An increase in the yield of the η ′ meson, proposed earlier as a signal of partial U A (1) restoration, is shown to create a " hole " in the low p t region of λ *. A comparison with NA44 data [1]...
