Description
We present the study of K0s and Lambda production performed with
the ALICE experiment at the LHC in Pb-Pb collisions at sqrt(sNN)=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 10 GeV/c.
They are also compared with the ones measured in pp events at the LHC energies of 0.9 and 7 TeV as well as in Au-Au collisions at sqrt(sNN)=0.2 TeV from RHIC.
