Probing hadronization and freeze-out with multiple strange hadrons and strange resonances

Abstract

I)The production of multiple strange baryons in pp interactions is studied. Here on can directly probe the microscopic decay of color flux tubes, allowing to differentiate between different string models and a statistical description of the hadronization. II)To analyse the different stages of a heavy ion collision the time evolution of the elastic and inelastic collision rates in central Pb+Pb interactions are studied. The microscopic simulation supports the idea of separated phases (non-equilibrium -> chemical freeze-out -> kinetic freeze-out) in the evolution of the system. The spectra and abundances of $\Lambda (1520)$, $K^0(892)$ and other resonances are used to study the break-up dynamics of the source between chemical and thermal freeze-out.
