eng Abstract:
Study of hadron properties inside nuclear matter at normal and high temperatures and baryon densities represents one of important topics of the present nuclear research. Several models predict change of effective masses and widths of hadrons due to the chiral symmetry restoration at extreme conditions of the nuclear matter. Existing experimental data do not allow unambiguous conclusions with respect to medium modifications due to the limited invariant mass resolution and separation. To improve and extend the existing experimental evidence the new High Acceptance DiElectron Spectrometer HADES was build at GSI, Darmstadt.
