The $m_{\\mathrm{T}}$ scaling predicted by pure hydrodynamic models appears to be broken in our data, which indicates the importance of the hadronic rescattering phase at LHC energies. A $k_{\\mathrm{T}}$ scaling of pion and kaon source radii is observed instead. The time of maximal emission of the system is estimated using the three-dimensional femtoscopic analysis for kaons. The measured emission time is larger than that of pions. Our observations are well supported by the hydrokinetic model predictions. \nFor correlation functions (Figure 2, Figure 3) the errors are statistical only, systematic uncertainties are equal to or less than the statistical errors.\nFor all other figures total errors are presented.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t1","@type":"Dataset","description":"Out projection of raw 3D LCMS K+- K+- correlation function for 0.2 < kT < 0.4 GeV/c bin.","name":"Figure 2a"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t2","@type":"Dataset","description":"Side projection of raw 3D LCMS K+- K+- correlation function for 0.2 < kT < 0.4 GeV/c bin","name":"Figure 2b"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t3","@type":"Dataset","description":"Long projection of raw 3D LCMS K+- K+- correlation function for 0.2 < kT < 0.4 GeV/c bin","name":"Figure 2c"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t4","@type":"Dataset","description":"Out projection of raw 3D LCMS KS KS correlation function for 1.0 < kT < 1.5 GeV/c bin","name":"Figure 3a"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t5","@type":"Dataset","description":"Side projection of raw 3D LCMS KS KS correlation function for 1.0 < kT < 1.5 GeV/c bin","name":"Figure 3b"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t6","@type":"Dataset","description":"Long projection of raw 3D LCMS KS KS correlation function for 1.0 < kT < 1.5 GeV/c bin","name":"Figure 3c"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t7","@type":"Dataset","description":"Rout vs. mT for PI+- PI+- for centrality 0-10%","name":"Figure 4a"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t8","@type":"Dataset","description":"Rside vs. mT for PI+- PI+- for centrality 0-10%","name":"Figure 4b"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t9","@type":"Dataset","description":"Rlong vs. mT for PI+- PI+- for centrality 0-10%","name":"Figure 4c"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t10","@type":"Dataset","description":"Rout vs. mT for PI+- PI+- for centrality 10-30%","name":"Figure 4d"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t11","@type":"Dataset","description":"Rside vs. mT for PI+- PI+- for centrality 10-30%","name":"Figure 4e"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t12","@type":"Dataset","description":"Rlong vs. mT for PI+- PI+- for centrality 10-30%","name":"Figure 4f"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t13","@type":"Dataset","description":"Rout vs. mT for PI+- PI+- for centrality 30-50%","name":"Figure 4g"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t14","@type":"Dataset","description":"Rside vs. mT for PI+- PI+- for centrality 30-50%","name":"Figure 4h"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t15","@type":"Dataset","description":"Rlong vs. mT for PI+- PI+- for centrality 30-50%","name":"Figure 4k"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t16","@type":"Dataset","description":"Rout vs. mT for PI+- PI+- for centrality 0-5%","name":"Figure 5a"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t17","@type":"Dataset","description":"Rside vs. mT for PI+- PI+- for centrality 0-5%","name":"Figure 5b"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t18","@type":"Dataset","description":"Rlong vs. mT for PI+- PI+- for centrality 0-5%","name":"Figure 5c"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t19","@type":"Dataset","description":"Ratio Rout/Rside vs. mT for PI+- PI+- for centrality 0-5%","name":"Figure 5d"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t20","@type":"Dataset","description":"Ratio Rout/Rside vs. mT for PI+- PI+- for centrality 0-10%","name":"Figure 7a"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t21","@type":"Dataset","description":"Ratio Rout/Rside vs. mT for PI+- PI+- for centrality 10-30%","name":"Figure 7b"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t22","@type":"Dataset","description":"Ratio Rout/Rside vs. mT for PI+- PI+- for centrality 30-50%","name":"Figure 7c"},{"@id":"https://doi.org/10.17182/hepdata.79128.v1/t23","@type":"Dataset","description":"Rlong^2 vs. mT for PI+- PI+- for centrality 0-5%","name":"Figure 8"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1621809?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/79128"}],"inLanguage":"en","name":"Kaon femtoscopy in Pb-Pb collisions at $\\sqrt{s_{\\rm{NN}}}$ = 2.76 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1621809?version=1","version":1}
