| Abstract | Hadronic resonances produced in high-energy collisions at the LHC are powerful tools to investigate the hadron formation and, at the same time, describe the state of strongly interacting matter formed in heavy-ion collisions. Due to their short lifetimes, resonances experience the competing effects of regeneration and rescattering of their decay products in the hadronic medium. The study of how these processes affect the experimentally measured yields can extend the current understanding of the properties of the hadronic phase and the mechanisms that determine the shape of particle transverse momentum spectra. The f$_0$(980) resonance was observed several years ago in pp scattering experiments. Despite a long history of experimental and theoretical studies, the nature of this short-lived resonance is far from being understood, and there is no agreement about its quark content. According to different models, it has been associated with a meson, considered as a tetraquark or as a KK molecule. The ALICE experiment’s excellent tracking and particle identification capabilities are exploited to measure the pT-differential spectrum and integrated yield of the f$_0$(980) meson produced in pp collisions at the energy of $\sqrt{s}$ = 5TeV. These results are discussed in comparison with models and the properties of other hadrons. The new preliminary results and overall status of light-flavour resonances production measured in pp, p-Pb, Pb-Pb and Xe-Xe collisions at different collision energies in ALICE are shown and discussed. The Blast-Wave model, several Monte Carlo models such as EPOS3 and MUSIC with UrQMD and SMASH afterburner and statistical hadronization model predictions are also shown and compared to the results. |
