The observed femtoscopic correlations are consistent with final-state interactions proceeding solely 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$^{\\rm +}$. Results of the present study are compared with those from identical-kaon femtoscopic studies also performed with pp collisions at $\\sqrt{s}=7$ TeV by ALICE and with a K$^0_{\\rm S}$K$^{\\rm \\pm}$ measurement in Pb-Pb collisions at $\\sqrt{s_{\\rm NN}}=2.76$ TeV. Combined with the Pb-Pb results, our pp analysis is found to be compatible with the interpretation of the $a_0(980)$ having a tetraquark structure instead of that of a diquark.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t1","@type":"Dataset","description":"Raw K0s K+ correlation function for all kT","name":"Figure 1a"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t2","@type":"Dataset","description":"Raw K0s K+ correlation function for kT < 0.85 GeV/c","name":"Figure 1b"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t3","@type":"Dataset","description":"Raw K0s K+ correlation function for kT > 0.85 GeV/c","name":"Figure 1c"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t4","@type":"Dataset","description":"C(k*)/(quadratic baseline) for K0s K+ and all kT, systematic uncertainties negligible for k*>0.06 GeV/c","name":"Figure 3a"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t5","@type":"Dataset","description":"C(k*)/(quadratic baseline) for K0s K+ and kT < 0.85 GeV/c, systematic uncertainties negligible for k*>0.06 GeV/c","name":"Figure 3b"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t6","@type":"Dataset","description":"C(k*)/(quadratic baseline) for K0s K+ and kT > 0.85 GeV/c, systematic uncertainties negligible for k*>0.06 GeV/c","name":"Figure 3c"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t7","@type":"Dataset","description":"C(k*)/(quadratic baseline) for K0s K- and all kT, systematic uncertainties negligible for k*>0.06 GeV/c","name":"Figure 3d"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t8","@type":"Dataset","description":"C(k*)/(quadratic baseline) for K0s K- and kT < 0.85 GeV/c, systematic uncertainties negligible for k*>0.06 GeV/c","name":"Figure 3e"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t9","@type":"Dataset","description":"C(k*)/(quadratic baseline) for K0s K- and kT > 0.85 GeV/c, systematic uncertainties negligible for k*>0.06 GeV/c","name":"Figure 3f"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t10","@type":"Dataset","description":"R vs. kT for 7 TeV pp averaged over K0s K+ and K0s K- with Achasov2 parameters","name":"Figure 5a_pp"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t11","@type":"Dataset","description":"R vs. kT for 2.76 TeV/nucleon Pb Pb averaged over K0s K+ and K0s K- with Achasov2 parameters","name":"Figure 5a_PbPb"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t12","@type":"Dataset","description":"lambda/purity vs. kT for 7 TeV pp averaged over K0s K+ and K0s K- with Achasov2 parameters","name":"Figure 5b_pp"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t13","@type":"Dataset","description":"lambda/purity vs. kT for 2.76 TeV/nucleon Pb Pb averaged over K0s K+ and K0s K- with Achasov2 parameters","name":"Figure 5b_PbPb"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t14","@type":"Dataset","description":"R vs. kT for 7 TeV pp averaged over K0s K+ and K0s K- and with Achasov2 parameters","name":"Figure 6a_K0Kch"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t15","@type":"Dataset","description":"R vs. kT for 7 TeV pp --> K0s K0s averaged over event multiplicity","name":"Figure 6a_K0K0"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t16","@type":"Dataset","description":"R vs. kT for 7 TeV pp --> K+- K+- averaged over event multiplicity and averaged between K+ and K-","name":"Figure 6a_KchKch"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t17","@type":"Dataset","description":"lambda/purity vs. kT for 7 TeV pp averaged over K0s K+ and K0s K- and with Achasov2 parameters","name":"Figure 6b_K0Kch"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t18","@type":"Dataset","description":"lambda/purity vs. kT for 7 TeV pp --> K0s K0s averaged over event multiplicity","name":"Figure 6b_K0K0"},{"@id":"https://doi.org/10.17182/hepdata.88298.v1/t19","@type":"Dataset","description":"lambda/purity vs. kT for 7 TeV pp --> K+- K+- averaged over event multiplicity and averaged between K+ and K-","name":"Figure 6b_KchKch"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1695028?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/88298"}],"inLanguage":"en","name":"Measuring K$^0_{\\rm S}$K$^{\\rm{\\pm}}$ interactions using pp collisions at $\\sqrt{s}=7$ TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1695028?version=1","version":1}
