Multi-strange baryon production in p-Pb collisions at $\sqrt{s_\mathbf{NN}}=5.02$ TeV

The multi-strange baryon yields in Pb Pb collisions have been shown to exhibit an enhancement relative to pp reactions. In this work, Ξ and Ω production rates have been measured with the ALICE experiment as a function of transverse momentum, pT , in p Pb collisions at a centre-of-mass energy of sNN=5.02 TeV . The results cover the kinematic ranges 0.6 GeV/c
