摘要：
Preliminary results by the ALICE Collaboration at the CERN Large Hadron Collider are presented for the multi-strange baryons in Pb-Pb collisions at root s(NN) = 2.76 TeV. Mid-rapidity transverse momentum spectra of the charged Xi and Omega baryons are shown in 0-90% centrality as well as in four centrality classes. The enhancements with respect to pp collisions at the same centre-of-mass energy have also been studied as a function of the mean number of participating nucleons and compared to existing measurements at SPS and RHIC.
