dc.description.abstractWe present the first measurements of femtoscopic correlations between the K0S and K± particles in pp collisions at √s = 7 TeV measured by the ALICE experiment. The observed femtoscopic correlationsare consistent with final-state interactions proceeding solely via the a0(980) resonance. The extractedkaon source radius and correlation strength parameters for K0SK− are found to be equal within theexperimental uncertainties to those for K0SK+. Results of the present study are compared with thosefrom identical-kaon femtoscopic studies also performed with pp collisions at √s = 7 TeV by ALICE andwith a K0SK± measurement in Pb–Pb collisions at √sNN = 2.76 TeV. Combined with the Pb–Pb results, ourpp analysis is found to be compatible with the interpretation of the a0(980) having a tetraquark structureinstead of that of a diquark.nb_NO
