$K^{0}_{s}$ and $\Lambda$ production in Pb--Pb collisions with the ALICE experiment
We present the study of K0s and \Lambda\ production performed with the ALICE experiment at the LHC in Pb--Pb collisions at $\sqrt{s_\mathrm{NN}}=2.76$ TeV and pp collisions at $\sqrt{s}=0.9$ and 7 TeV. The K0s and \Lambda\ particles are reconstructed via their V0 decay topology allowing their identi...

Sumario: | We present the study of K0s and \Lambda\ production performed with the ALICE experiment at the LHC in Pb--Pb collisions at $\sqrt{s_\mathrm{NN}}=2.76$ TeV and pp collisions at $\sqrt{s}=0.9$ and 7 TeV. The K0s and \Lambda\ particles are reconstructed via their V0 decay topology allowing their identification up to high transverse momenta. The corresponding baryon/meson ratios as a function of transverse momentum are extracted for Pb--Pb collisions in centrality bins and in the transverse momentum range from 1 to 6 GeV/c. They are also compared with those measured in pp events at the LHC energies of 0.9 and 7 TeV as well as in Au--Au collisions at $\sqrt{s_\mathrm{NN}} = 62.4$ and 200 GeV from RHIC. |
