Collision centrality and rapidity dependences of the transverse momentum spectra and particle ratios are presented. Particle mass and centrality dependence of the average transverse momenta of $\\Lambda$ and $K^0_S$ are compared with other strange particles, providing evidence of the development of hadronic rescattering in such collisions. The 4$\\pi$ yields of each of these strange hadrons show a consistent centrality dependence. Discussions on radial flow, the strange hadron production mechanism, and properties of the medium created in such collisions are presented together with results from hadronic transport and thermal model calculations.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t1","@type":"Dataset","description":"dN/dy of lambda for different centrality bins.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t2","@type":"Dataset","description":"dN/dy of Ks0 for different centrality bins.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t3","@type":"Dataset","description":"Rapidity dependence of Lambda/p for different centrality bins.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t4","@type":"Dataset","description":"Mean transverse momentum $\\langle p_{T} \\rangle$ for $\\Lambda$ and $K^{0}_{S}$ at mid-rapidity as a function of $N_{\\text{part}}$ at 3 GeV.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t5","@type":"Dataset","description":"Hadron 4$\\pi$ yields per mean number of participants yield as a function of $N_{\\text{part}}$.","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t6","@type":"Dataset","description":"Mid-rapidity yield ratios of $\\Lambda/p$, $\\Xi/\\Lambda$, and $K^0_{S}/\\Lambda$ at 3 GeV.","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t7","@type":"Dataset","description":"The transverse-momentum spectra of $\\Lambda$ for different rapidities.","name":"Table 7 0-10%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t8","@type":"Dataset","description":"The transverse-momentum spectra of $\\Lambda$ for different rapidities.","name":"Table 7 10-20%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t9","@type":"Dataset","description":"The transverse-momentum spectra of $\\Lambda$ for different rapidities.","name":"Table 7 20-30%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t10","@type":"Dataset","description":"The transverse-momentum spectra of $\\Lambda$ for different rapidities.","name":"Table 7 30-40%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t11","@type":"Dataset","description":"The transverse-momentum spectra of $\\Lambda$ for different rapidities.","name":"Table 7 40-60%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t12","@type":"Dataset","description":"The transverse-momentum spectra of $\\Lambda$ for different rapidities.","name":"Table 7 60-80%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t13","@type":"Dataset","description":"The transverse-momentum spectra of $K^{0}_{S}$ for different rapidities.","name":"Table 8 0-10%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t14","@type":"Dataset","description":"The transverse-momentum spectra of $K^{0}_{S}$ for different rapidities.","name":"Table 8 10-20%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t15","@type":"Dataset","description":"The transverse-momentum spectra of $K^{0}_{S}$ for different rapidities.","name":"Table 8 20-30%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t16","@type":"Dataset","description":"The transverse-momentum spectra of $K^{0}_{S}$ for different rapidities.","name":"Table 8 30-40%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t17","@type":"Dataset","description":"The transverse-momentum spectra of $K^{0}_{S}$ for different rapidities.","name":"Table 8 40-60%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t18","@type":"Dataset","description":"The transverse-momentum spectra of $K^{0}_{S}$ for different rapidities.","name":"Table 8 60-80%"},{"@id":"https://doi.org/10.17182/hepdata.153884.v1/t19","@type":"Dataset","description":"Hadron mass dependence of mean transverse momentum $\\langle p_{T} \\rangle$.","name":"Table 9"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2807679?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/153884"}],"inLanguage":"en","name":"Strangeness Production in $\\sqrt{s_{\\rm NN}}=3$ GeV Au+Au Collisions at RHIC","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2807679?version=1","version":1}
