Modification of hadron properties in compressed nuclear matter: Recent results from the FOPI collaboration. — •Victoria Zinyuk for the FOPI collaboration — Universität Heidelberg, Heidelberg, Germany
In compressed baryonic matter the properties of hadrons are believed to alter as a result of various non-trivial in -medium effects such as the partial restoration of the spontaneously broken chiral symmetry, the modified baryon-meson couplings and the nuclear potential. Possible modification of properties like mass, width and dispersion relation can be experimentally observed for strange particles produced sub- or close-to-production threshold energies. The FOPI detector at SIS18 provides a possibility to investigate the production and propagation of charged and neutral strange particles in a wide range of phase space. This presentation gives an overview of FOPI’s recent results on collective behavior and modification of phase space distribution for strange mesons at densities up to 2-3 ρ0, investigated in heavy-ion collisions, and at normal nuclear matter density as observed in pion-induced reactions.
