Abstract
The ALICE experiment at the LHC has measured the production of strange hadrons and resonances in Pb-Pb and pp collisions at unprecedented high beam energies. The study of strange hadrons and resonances helps us to understand the properties of the medium created in the heavy-ion collisions and its evolution. We present the yields (dN/dy) at mid-rapidity for strange hadrons (Î,Îâ,Ωâ, their anti-particles and KS0) and resonances (Ï and Kâ0) for several collision centrality intervals. The results from Pb-Pb collisions at sNN=2.76TeV are presented and compared to corresponding results from pp collisions and lower energy measurements. Baryon to meson ratios and resonance to non-resonance particle ratios relative to pp collisions are shown as a function of collision centrality and compared with the results at lower energies.
