ABSTRACT
The production of ${\rm\Xi}^-$ and ${\rm\Omega}^-$ baryons their anti-particles in Pb-Pb collisions at $\sqrt{s_{\rm NN}}$ = 2.76 TeV has been measured using the ALICE detector. transverse momentum spectra mid-rapidity ($|y| < 0.5$) for charged $\rm\Xi$ $\rm\Omega$ hyperons have studied range $0.6 p_{\rm T} 8.0$ GeV/$c$ $1.2 7.0$ GeV/$c$, respectively, several centrality intervals (from most central 0-10% to peripheral 60-80% collisions). These compared with predictions recent hydrodynamic models. In particular, Krak${\'o}$w EPOS models give a satisfactory description data, latter covering wider $p_{\rm T}$ range. Mid-rapidity yields, integrated over T}$, determined. hyperon-to-pion ratios are similar those RHIC: they rise smoothly up $\langle N_{\rm part}\rangle$~150 saturate thereafter. enhancements (yields per participant nucleon relative pp collisions) increase both strangeness content baryon centrality, but less pronounced than lower energies.
