Description
The lifetimes of short-lived hadronic resonances are comparable to that of the hadronic phase which is present in the late stages of the evolution of heavy-ion collisions. Thus, these resonances are sensitive to the re-scattering and regeneration processes in the time interval between the chemical and kinetic freeze-out, which might affect the observed resonance yields. Recently, the centrality dependent suppression of several resonances has been observed in Pb-Pb collisions, which possibly indicates the dominance of re-scattering over regeneration processes. In this talk, we present recent results on short-lived hadronic resonances obtained by the ALICE experiment in Pb-Pb collisions at LHC energies for $\mathrm{\rho^0}$, $\mathrm{K^{*0}}$, $\mathrm{\phi}$, $\mathrm{\Lambda^*}$ and $\mathrm{\Xi^*}$. Results on transverse momentum spectra, yields and their ratios to long-lived particles, and nuclear modification factors will be discussed. The findings will be compared with model predictions and measurements at lower energies.
