The Electromagnetic Response of Resonance Matter and Other Strange Observations

Popis výsledku v původním jazyce

The matter formed in central heavy-ion collisions at a few GeV per nucleon is commonly understood as resonance matter, a gas of nucleons and excited baryonic states with a substantial contribution from mesonic, mostly pionic excitations. Yet, in the initial phase of the reaction the system is compressed to beyond nuclear ground state density and hence substantial modifications of the hadron properties are expected to occur. It is conjectured that at high enough densities hadronic degrees of freedom would finally disappear and a chirally restored phase of quarks would emerge. In this contribution we present key results on in-medium properties of hadrons obtained by the High Acceptance DiElectron Spectrometer. The spectral distribution of virtual photons emitted from the collision zone of A+A collisions indicates strong medium effects beyond those resulting from a pure superposition of individual N+N collisions.
