Description

In this talk we present a comprehensive set of measurements on hadronic resonance production with ALICE, including new results from the LHC Run II . Transverse momentum spectra, integrated yields, mean transverse momenta, particle ratios and nuclear modification factors will be presented for $\rho (770{)}^0$, $K^{\ast }(892{)}^0$, $\varphi (1020)$, $\mathrm{\Sigma }(1385{)}^{\pm }$, $\mathrm{\Lambda }(1520)$ and $\mathrm{\Xi }(1530{)}^0$ as a function of multiplicity/centrality in Pb-Pb collisions. New data for $K^{\ast }(892{)}^0$ and $\varphi (1020)$ in Pb-Pb collisions at $\sqrt{s_{\mathrm{NN}}}$ = 5.02 TeV are used to study the energy dependence of the hadronic interactions and of jet quenching. The first results from the recent Xe-Xe run will also be shown. The obtained results give us the possibility to constrain the lifetime of the hadronic phase. They are discussed and compared to predictions of models such as grand-canonical thermal models, PYTHIA, PHSD and EPOS3 event generators and with lower energy measurements.
