description <!--HTML--><p><span><span><span><span><span><span>ALICE measurements have shown that the inclusive production of (multi-)strange particles smoothly increases as a function of the size of the collision system, as measured by charged-particle multiplicity in pp, p-Pb, and Pb-Pb collisions. Further investigation revealed an overall enhancement in the yield of strange baryons relative to mesons in collisions with higher multiplicity for all systems, possibly due to the effects of collective radial flow and recombination of quarks.
