Abstract

The measurement of hadronic resonance production in heavy-ion col- lisions at the LHC has led to observing a prolonged hadronic phase after hadronization. Due to their short lifetimes, resonances experience the competing effects of re-generation and rescattering of their decay products in the hadronic medium. Studying 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 pT spectra. This contribution presents new preliminary results on the production of Λ(1520) resonance measured in Pb-Pb col- lisions at √ sNN = 5.02 TeV with the ALICE detector at the LHC. These results on Λ(1520) (lifetime, τ = 12.6 fm/c) are compared with a set of hadronic reso- nances with a lifetime span of 1 to 46 fm/c such as ρ(770)0, K∗(892)0, Σ(1385)±, Ξ(1530)0 and φ(1020) measured by the ALICE experiment. The shape of particle transverse momentum (pT), mean pT and particle ratios are compared with those predicted from the Blast-Wave, MUSIC with SMASH afterburner and statistical hadronization model predictions.
