Description
Hadron modifications in hot and/or dense nuclear matter have been predicted by many model calculations. They are commonly discussed in scenarios of chiral symmetry restoration or hadronic many body effects (for recent review see [1]). Experiments with photon, proton and heavy ion beams are used to probe hadron properties in nuclear matter of various forms: from cold nucleus to hot and compressed hadron gas. Most of information have been gathered for light vector mesons (ρ/ω/φ) which, due to their short life time, decay to large extent inside the medium. Decay channels involving dileptons and hadrons have been selected to measure meson line shape and/or nuclear transparency. Significant medium effects have been observed and interpreted in terms of meson broadening. Moreover, measurement of dileptons from heavy ion collisions allows to separate contribution from dense phase and characterize its properties. Review of recent experimental results, focused on low energy domain, will be presented.
