The ALICE measurement of K$^0_{\\rm S}$ and $\\rm\\Lambda$ production at mid-rapidity in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}} = 2.76$ TeV is presented. The transverse momentum ($p_{\\rm T}$) spectra are shown for several collision centrality intervals and in the $p_{\\rm T}$ range from 0.4 GeV/$c$ (0.6 GeV/$c$ for $\\rm\\Lambda$) to 12 GeV/$c$. The $p_{\\rm T}$ dependence of the $\\rm \\Lambda$/K$^0_{\\rm S}$ ratios exhibits maxima in the vicinity of 3 GeV/$c$, and the positions of the maxima shift towards higher $p_{\\rm T}$ with increasing collision centrality. The magnitude of these maxima increases by almost a factor of three between most peripheral and most central Pb-Pb collisions. This baryon excess at intermediate $p_{\\rm T}$ is not observed in pp interactions at sqrt(s) = 0.9 TeV and at sqrt(s) = 7 TeV. Qualitatively, the baryon enhancement in heavy-ion collisions is expected from radial flow. However, the measured $p_{\\rm T}$ spectra above 2 GeV/$c$ progressively decouple from hydrodynamical-model calculations. For higher values of $p_{\\rm T}$, models that incorporate the influence of the medium on the fragmentation and hadronization processes describe qualitatively the $p_{\\rm T}$ dependence of the $\\rm\\Lambda$/K$^0_{\\rm S}$ ratio\nNote:(Update APR 2016) total integrated mid-rapidity yields for Lambda and K0s added.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t1","@type":"Dataset","description":"pT spectra of K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 0.0-5.0%.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t2","@type":"Dataset","description":"pT spectra of K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 5.0-10.0%.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t3","@type":"Dataset","description":"pT spectra of K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 10.0-20.0%.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t4","@type":"Dataset","description":"pT spectra of K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 20.0-40.0%.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t5","@type":"Dataset","description":"pT spectra of K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 40.0-60.0%.","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t6","@type":"Dataset","description":"pT spectra of K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 60.0-80.0%.","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t7","@type":"Dataset","description":"pT spectra of K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 80.0-90.0%.","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t8","@type":"Dataset","description":"pT spectra of Lambda in the rapidity range -0.5<y<0.5 in the centrality interval 0.0-5.0%.","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t9","@type":"Dataset","description":"pT spectra of Lambda in the rapidity range -0.5<y<0.5 in the centrality interval 5.0-10.0%.","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t10","@type":"Dataset","description":"pT spectra of Lambda in the rapidity range -0.5<y<0.5 in the centrality interval 10.0-20.0%.","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t11","@type":"Dataset","description":"pT spectra of Lambda in the rapidity range -0.5<y<0.5 in the centrality interval 20.0-40.0%.","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t12","@type":"Dataset","description":"pT spectra of Lambda in the rapidity range -0.5<y<0.5 in the centrality interval 40.0-60.0%.","name":"Table 12"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t13","@type":"Dataset","description":"pT spectra of Lambda in the rapidity range -0.5<y<0.5 in the centrality interval 60.0-80.0%.","name":"Table 13"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t14","@type":"Dataset","description":"pT spectra of Lambda in the rapidity range -0.5<y<0.5 in the centrality interval 80.0-90.0%.","name":"Table 14"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t15","@type":"Dataset","description":"Ratio of Lambda/K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 0.0-5.0%.","name":"Table 15"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t16","@type":"Dataset","description":"Ratio of Lambda/K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 5.0-10.0%.","name":"Table 16"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t17","@type":"Dataset","description":"Ratio of Lambda/K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 10.0-20.0%.","name":"Table 17"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t18","@type":"Dataset","description":"Ratio of Lambda/K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 20.0-40.0%.","name":"Table 18"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t19","@type":"Dataset","description":"Ratio of Lambda/K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 40.0-60.0%.","name":"Table 19"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t20","@type":"Dataset","description":"Ratio of Lambda/K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 60.0-80.0%.","name":"Table 20"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t21","@type":"Dataset","description":"Ratio of Lambda/K0Short in the rapidity range -0.5<y<0.5 in the centrality interval 80.0-90.0%.","name":"Table 21"},{"@id":"https://doi.org/10.17182/hepdata.61857.v1/t22","@type":"Dataset","description":"Total integrated mid-rapidity yields for K0Short in the rapidity range -0.5<y<0.5 for different centrality intervals.
