This study extends similar measurements performed at $\\sqrt{s}=7$ and $13~\\mathrm{TeV}$ to a lower energy regime, improving the statistical precision and extending the measurement to previously unexplored low-multiplicity regions. While $\\rm K^{0}_{\\mathrm{S}}$, $\\Lambda$, and $\\Xi$ yields can be described with a linear multiplicity dependence within uncertainties, the $\\Omega$ yields follow a significantly faster-than-linear increasing trend. For all analysed particles, the overall production rate is consistent with those observed at higher energy and at similar multiplicity densities. Transverse-momentum distributions are observed to evolve with multiplicity. Several state-of-the-art QCD-inspired Monte Carlo models have been compared to the data. Models can qualitatively describe the transverse-momentum spectra and the $\\Lambda/\\rm K^{0}_{\\mathrm{S}}$ spectral ratio only if collectivity is introduced in the evolution of the system.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t1","@type":"Dataset","description":"$p_{\\mathrm{T}}$ distributions at midrapidity for $\\rm K^{0}_{\\mathrm{S}}$ for multiplicity classes and $\\mathrm{INEL}>0$.","name":"Figure 1a"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t2","@type":"Dataset","description":"$p_{\\mathrm{T}}$ distributions at midrapidity for $\\Lambda+\\bar{\\Lambda}$ for multiplicity classes and $\\mathrm{INEL}>0$.","name":"Figure 1b"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t3","@type":"Dataset","description":"$p_{\\mathrm{T}}$ distributions at midrapidity for $\\Xi^{-}+\\bar{\\Xi}^{+}$ for multiplicity classes and $\\mathrm{INEL}>0$.","name":"Figure 1c"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t4","@type":"Dataset","description":"$p_{\\mathrm{T}}$ distributions at midrapidity for $\\Omega^{-}+\\bar{\\Omega}^{+}$ for multiplicity classes and $\\mathrm{INEL}>0$.","name":"Figure 1d"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t5","@type":"Dataset","description":"$\\langle p_{\\mathrm{T}} \\rangle$ of $\\rm K^{0}_{\\rm S}$ in pp collisions at $\\sqrt{s}=5.02~\\mathrm{TeV}$ at midrapidity as a function of the event...","name":"Figure 2a"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t6","@type":"Dataset","description":"$\\langle p_{\\mathrm{T}} \\rangle$ of $\\Lambda+\\bar{\\Lambda}$ in pp collisions at $\\sqrt{s}=5.02~\\mathrm{TeV}$ at midrapidity as a function of the event multiplicity.","name":"Figure 2b"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t7","@type":"Dataset","description":"$\\langle p_{\\mathrm{T}} \\rangle$ of $\\Xi^{-}+\\bar{\\Xi}^{+}$ in pp collisions at $\\sqrt{s}=5.02~\\mathrm{TeV}$ at midrapidity as a function of the event multiplicity.","name":"Figure 2c"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t8","@type":"Dataset","description":"$\\langle p_{\\mathrm{T}} \\rangle$ of $\\Omega^{-}+\\bar{\\Omega}^{+}$ in pp collisions at $\\sqrt{s}=5.02~\\mathrm{TeV}$ at midrapidity as a function of the event multiplicity.","name":"Figure 2d"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t9","@type":"Dataset","description":"$p_{\\mathrm{T}}$ distribution of the $\\Lambda/ \\rm K^{0}_{\\mathrm{S}}$ ratio in pp collisions at $\\sqrt{s}=5.02~\\mathrm{TeV}$ and at midrapidity, for different multiplicity classes.","name":"Figure 3"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t10","@type":"Dataset","description":"$p_{\\mathrm{T}}$-integrated yields for $\\rm K^{0}_{\\rm S}$ in pp collisions at $\\sqrt{s}=5.02~\\mathrm{TeV}$ at midrapidity as a function of the event multiplicity.","name":"Figure 4a"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t11","@type":"Dataset","description":"$p_{\\mathrm{T}}$-integrated yields for $\\Lambda+\\bar{\\Lambda}$ in pp collisions at $\\sqrt{s}=5.02~\\mathrm{TeV}$ at midrapidity as a function of the event multiplicity.","name":"Figure 4b"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t12","@type":"Dataset","description":"$p_{\\mathrm{T}}$-integrated yields for $\\Xi^{-}+\\bar{\\Xi}^{+}$ in pp collisions at $\\sqrt{s}=5.02~\\mathrm{TeV}$ at midrapidity as a function of the event multiplicity.","name":"Figure 4c"},{"@id":"https://doi.org/10.17182/hepdata.180658.v1/t13","@type":"Dataset","description":"$p_{\\mathrm{T}}$-integrated yields for $\\Omega^{-}+\\bar{\\Omega}^{+}$ in pp collisions at $\\sqrt{s}=5.02~\\mathrm{TeV}$ at midrapidity as a function of the event multiplicity.","name":"Figure 4d"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins3082917?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/180658"}],"inLanguage":"en","name":"Strangeness production as a function of charged-particle multiplicity in proton-proton collisions at ${\\bf \\sqrt{s}~=~5.02}$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins3082917?version=1","version":1}
