    <subfield code="a">&lt;p&gt;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&amp;lt;pT&amp;lt;7.2 GeV/c and 0.8 GeV/c&amp;lt;pT&amp;lt;5 GeV/c , for Ξ and Ω respectively, in the common rapidity interval −0.5&amp;lt;yCMS&amp;lt;0 . Multi-strange baryons have been identified by reconstructing their weak decays into charged particles. The pT spectra are analysed as a function of event charged-particle multiplicity, which in p Pb collisions ranges over one order of magnitude and lies between those observed in pp and Pb Pb collisions. The measured pT distributions are compared to the expectations from a Blast-Wave model. The parameters which describe the production of lighter hadron species also describe the hyperon spectra in high multiplicity p Pb collisions. The yield of hyperons relative to charged pions is studied and compared with results from pp and Pb Pb collisions. A continuous increase in the yield ratios as a function of multiplicity is observed in p Pb data, the values of which range from those measured in minimum bias pp to the ones in Pb Pb collisions. A statistical model qualitatively describes this multiplicity dependence using a canonical suppression mechanism, in which the small volume causes a relative reduction of hadron production dependent on the strangeness content of the hyperon.&lt;/p&gt;</subfield>
