Multi-strange baryon production at mid-rapidity in Pb–Pb collisions at sNN=2.76 TeV

The production of Ξ−Ξ− and Ω−Ω− baryons and their anti-particles in Pb–Pb collisions at sNN=2.76 TeV has been measured using the ALICE detector. The transverse momentum spectra at mid-rapidity (|y|<0.5|y|<0.5) for charged Ξ and Ω hyperons have been studied in the range 0.6
