Hadronic resonances with different lifetimes are very useful to probe the so-called “hadronic phase” which characterises the latest stages in the evolution of the system created in heavy- ion collisions. As they decay in the same timescale, of the order of 1 to 10 fm/c, as the decoupling time of the system, resonances are good candidates to investigate the interplay between particle rescattering and regeneration. In addition, the measurement of resonances having different masses, quantum numbers and quark content can contribute to the understanding of strangeness production, the processes that determine the shapes of particle momentum spectra, and the possible onset of collective effects in small systems. In this seminar, after a short introduction on the characteristics of heavy-ion collisions, the latest results on 𝜌(770), K*(892), f(980), 𝜙(1020), Σ(1385), Λ(1520), Ξ(1530) production in pp, p-Pb, Pb-Pb and Xe-Xe collisions at different energies will be presented. These results include system-size and collision-energy evolution of transverse momentum spectra, integrated yields, mean transverse momenta and particle ratios. Comparisons with theoretical models will also be discussed.
