Exploring the hadronic phase of relativistic heavy-ion collisions with resonances in ALICE

Short-lived resonances are a good tool to study the hadronic phase that characterizes the late-stage evolution of heavy-ion collisions. Regeneration and rescattering processes taking part for resonances in the hadronic phase modify their measured yields. This can be studied by measuring resonance to...

description Short-lived resonances are a good tool to study the hadronic phase that characterizes the late-stage evolution of heavy-ion collisions. Regeneration and rescattering processes taking part for resonances in the hadronic phase modify their measured yields. This can be studied by measuring resonance to stable particle yield ratios as a function of system size and comparing them to model predictions with and without hadronic interactions. With the excellent tracking and particle identification capabilities that ALICE has been endowed with, a comprehensive set of both mesonic and baryonic resonances have been measured. Recent results on resonance production in pp, p$-$Pb, Xe$-$Xe and Pb$-$Pb collisions at various centre of mass energies are presented. Recent results on K*$^{\pm}$(892), $\Sigma$*$^{\pm}$(1385) and $\Xi$*$^{0}$(1820), are presented. The results are further compared to lower energy measurements and different model predictions wherever available.
