Probing the hadronic phase with resonances of different lifetimes in Pb-Pb collisions with ALICE

The ALICE experiment has measured the production of a rich set of hadronic resonances, such as ρ(770)0, K*(892)0, ϕ(1020), ∑±(1385), Λ(1520) and Ξ*0 in pp, p-Pb and Pb-Pb collisions at various energies at the LHC. A comprehensive overview and the latest results are presented in this paper. Special f...

description The ALICE experiment has measured the production of a rich set of hadronic resonances, such as ρ(770)0, K*(892)0, ϕ(1020), ∑±(1385), Λ(1520) and Ξ*0 in pp, p-Pb and Pb-Pb collisions at various energies at the LHC. A comprehensive overview and the latest results are presented in this paper. Special focus is given to the role of hadronic resonances for the study of final-state effects in high-energy collisions. In particular, the measurement of resonance production in heavy-ion collisions has the capability to provide insight into the existence of a prolonged hadronic phase after hadronisation. The observation of the suppression of the production of Λ(1520) resonance in central Pb-Pb collisions at =2.76 TeV adds further support to the existence of such a dense hadronic phase, as already evidenced by the ratios K*(892)0/K and ρ(770)0/π.

A comprehensive overview and the latest results are presented in this paper. Special focus is given to the role of hadronic resonances for the study of final-state effects in high-energy collisions. In particular, the measurement of resonance production in heavy-ion collisions has the capability to provide insight into the existence of a prolonged hadronic phase after hadronisation. The observation of the suppression of the production of $\Lambda(1520)$ resonance in central Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV adds further support to the existence of such a dense hadronic phase, as already evidenced by the ratios ${\rm K}^{\ast}(892)^{0}$/${\rm K}$ and $\rho(770)^{0}$/$\pi$.arXiv:1711.02408oai:cds.cern.ch:22922952018
