The analysis was performed on the data from Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}=2.76$ TeV measured by the ALICE experiment. The observed femtoscopic correlations are consistent with final-state interactions proceeding via the $a_0(980)$ resonance. The extracted kaon source radius and correlation strength parameters for K$^0_{\\rm S}$K$^{\\rm -}$ are found to be equal within the experimental uncertainties to those for K$^0_{\\rm S}$K$^{\\rm +}$. Comparing the results of the present study with those from published identical-kaon femtoscopic studies by ALICE, mass and coupling parameters for the $a_0$ resonance are constrained. Our results are also compatible with the interpretation of the $a_0$ having a tetraquark structure over that of a diquark.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t1","@type":"Dataset","description":"Raw K0s K+ correlation function for all kT bin","name":"Figure 1a"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t2","@type":"Dataset","description":"Raw K0s K+ correlation function for kT < 0.675 GeV/c bin","name":"Figure 1b"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t3","@type":"Dataset","description":"Raw K0s K+ correlation function for kT > 0.675 GeV/c bin","name":"Figure 1c"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t4","@type":"Dataset","description":"C(k*)/(linear baseline fit) for K0s K+ and all kT bin","name":"Figure 2a"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t5","@type":"Dataset","description":"C(k*)/(linear baseline fit) for K0s K+ and kT < 0.675 GeV/c bin","name":"Figure 2b"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t6","@type":"Dataset","description":"C(k*)/(linear baseline fit) for K0s K+ and kT > 0.675 GeV/c bin","name":"Figure 2c"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t7","@type":"Dataset","description":"C(k*)/(linear baseline fit) for K0s K- and all kT bin","name":"Figure 2d"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t8","@type":"Dataset","description":"C(k*)/(linear baseline fit) for K0s K- and kT < 0.675 GeV/c bin","name":"Figure 2e"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t9","@type":"Dataset","description":"C(k*)/(linear baseline fit) for K0s K- and kT > 0.675 GeV/c bin","name":"Figure 2f"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t10","@type":"Dataset","description":"R vs. kT for K0s K- with Achasov1 parameters","name":"Figure 3a"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t11","@type":"Dataset","description":"lambda vs. kT for K0s K- with Achasov1 parameters","name":"Figure 3b"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t12","@type":"Dataset","description":"R vs. kT for K0s K+- with Achasov1 parameters and linear fit","name":"Figure 3c"},{"@id":"https://doi.org/10.17182/hepdata.80522.v1/t13","@type":"Dataset","description":"lambda vs. kT for K0s K+- with Achasov1 parameters and linear fit","name":"Figure 3d"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1599554?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/80522"}],"inLanguage":"en","name":"Measuring K$^0_{\\rm S}$K$^{\\rm \\pm}$ interactions using 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/ins1599554?version=1","version":1}
