Baryon-rich matter in heavy-ion collisions: from stopping to particle production and calibrated strange probes
Seminarium zostanie wygłoszone w języku angielskim.
The seminar will be held in English.
Heavy-ion collisions at SIS18 and FAIR energies explore strongly interacting matter at high net-baryon density, but the character of thecollision system changes substantially with beam energy. At the lowest energies, baryon stopping and cluster formation dominate the final state, while with increasing collision energy particle production becomes progressively more important and the hadronic composition shiftstowards a larger mesonic component. I will discuss how this evolution can be quantified using hadron yields, stopping observables and thecombined free-plus-bound baryonic final state, and why a controlled description of these bulk dynamics is essential for interpreting moreselective probes. Particular emphasis will be placed on strangeness production: its strong near-threshold energy dependence provides highsensitivity to the evolving medium, but also makes it particularly dependent on the underlying reaction dynamics. This motivates a strategy in which strange hadrons are used as calibrated probes of baryon-rich matter across the HADES and FAIR energy range.
