Description
The microscopic properties of the strong-interaction matter under extreme conditions of temperature and density is a topic of great current interest. Despite 18 orders of magnitude difference in system size and time, the conditions present in heavy-ion collisions share great overlap with the conditions of the strong-interaction matter in neutron-star mergers. The possibility to form and explore in the laboratory strong-interaction matter under extreme conditions is truly fascinating.
In this talk I will focus on relevantobservables to study criticality, emissivity, vorticity and equation-of-state of baryon rich matter. New experimental results on the mechanisms of strangeness production, the emissivity of matter and the role of baryonic resonances herein will be discussed. The multi-differential representations of hadron and dilepton spectra, collective effects and particle correlations will be confronted with results of other experiments as well as with hitherto model calculations. The results obtained for heavy-ion collisions are confronted to studies of elementary reactions serving as a reference for medium effects.
