Hadronic resonances play an important role in the study of the physics of heavy-ion collisions. In these proceedings, we discuss how the resonances can probe the reaction dynamics, the strangeness production and the properties of the hadronic phase in heavy-ion collisions at center-of-mass energies of sNN = 4–11 GeV. The resonance properties predicted by the general-purpose event generators are found to be very sensitive to the properties and space-time evolution of the medium produced in heavy-ion collisions.

AbstractIn a recent article we presented a model for hadronic rescattering, and some results were shown for $$\mathrm {p}\mathrm {p}$$ p p collisions at LHC energies. In order to extend the studies to $$\mathrm {p}\mathrm {A}$$ p A and $$\mathrm {A}\mathrm {A}$$ A A collisions, the Angantyr model for heavy-ion collisions is taken as the starting point. Both these models are implemented within the general-purpose Monte Carlo event generator Pythia, which makes the matching reasonably straightforward, and allows for detailed studies of the full space–time evolution. The rescattering rate is significantly higher than in $$\mathrm {p}\mathrm {p}$$ p p , especially for central $$\mathrm {A}\mathrm {A}$$ A A collisions, where the typical primary hadron rescatters several times. We study the impact of rescattering on a number of distributions, such as $$p_{\perp }$$ p ⊥ and $$\eta $$ η spectra, and the space–time evolution of the whole collision process. Notably rescattering is shown to give a significant contribution to elliptic flow in $$\mathrm {XeXe}$$ XeXe and $$\mathrm {PbPb}$$ PbPb , and to give a nontrivial impact on charm production.

Hydrodynamics Equations

Three subjects are considered here: the relativistic hydrodynamics equations for a boost-invariant expanding fluid; the fuzzy bag model for the pressure which recently appeared in (QCD) phenomenology; and the early space-time evolution of the QCD matter, drawn from model studies, which can also be expected to arise in realistic fluid dynamics relevant to heavy ion collisions at LHC.
