Abstract
Measurements of strange hadron ($K_S^0$, $Λ+\overline{Λ}$, and $_{\Xi^- + \overline{\Xi}^+}$) transverse momentum spectra in $pp$, $pPb$, and PbPb collisions are presented over a wide range of rapidity and event charged-particle multiplicity. The data were collected with the CMS detector at the CERN LHC in $pp$ collisions at $\sqrt{s}=7$ TeV, $pPb$ collisions at $\sqrt{s_{NN}}$=5.02TeV, and PbPb collisions at $\sqrt{s_{NN}}$=2.76TeV. The average transverse kinetic energy is found to increase with multiplicity, at a faster rate for heavier strange particle species in all systems. At similar multiplicities, the difference in average transverse kinetic energy between different particle species is observed to be larger for $pp$ and $pPb$ events than for PbPb events. In $pPb$ collisions, the average transverse kinetic energy is found to be slightly larger in the Pb-going direction than in the p-going direction for events with large multiplicity. The spectra are compared to models motivated by hydrodynamics.
