【 摘 要 】

In heavy ion collisions a fireball of hot and dense matter is created. Short lived hadronic resonances are sensitive to the medium properties, in particular to the temperature, density and system size. Resonance yields and momentum distributions are used to gain insight into the hadronic phase, its expansion velocity and time duration. The multiplicity dependent hadronic resonance production in p-p, p-Pb and Pb-Pb collisions will be discussed within the context of the possible extended hadronic and partonic phase. The experimental results will be compared to EPOS+UrQMD model calculations to discuss the system size dependent interactions of the hadronic medium on various resonances. Small systems such as p-p and p-Pb collisions will be discussed with respect to resonance and strange particle measurements.
