| contents | In this work, we show how $π^+ K_S$ femtoscopic correlations, recently reported by ALICE collaboration in $ pp $ collisions, can be well described taking into account relativistic corrections and using realistic $ πK $ interactions. These are obtained from a dispersive analysis of scattering data, which provides an accurate and model-independent description of the $ κ/K^*_0(700) $ resonance pole. The chiral symmetry suppression of the $ πK $ interactions at low energies and the non-ordinary features of the $ κ/K^*_0(700) $ seem to suggest that the $ π^+ K_S $ source radius might be surprisingly smaller than for other hadronic processes when using the standard and simple Lednicky-Lyuboshits factorization approximation. |
