Sažetak
We present the first ever measurements of femtoscopic correlations between the and K± particles. The analysis was performed on the data from Pb–Pb collisions at TeV measured by the ALICE experiment. The observed femtoscopic correlations are consistent with final-state interactions proceeding via the resonance. The extracted kaon source radius and correlation strength parameters for are found to be equal within the experimental uncertainties to those for . Comparing the results of the present study with those from published identical-kaon femtoscopic studies by ALICE, mass and coupling parameters for the resonance are tested. Our results are also compatible with the interpretation of the having a tetraquark structure instead of that of a diquark.
