| The first measurements of the scattering parameters of Λ K pairs in all three charge combinations (Λ K+, Λ K−, and Λ KS 0) are presented. The results are achieved through a femtoscopic analysis of Λ K correlations in Pb-Pb collisions at s NN= 2.76 TeV recorded by ALICE at the Large Hadron Collider. The femtoscopic correlations result from strong final-state interactions and are fit with a parametrization allowing for both the characterization of the pair emission source and the measurement of the scattering parameters for the particle pairs. Extensive studies with the THERMINATOR 2 event generator provide a good description of the nonfemtoscopic background, which results mainly from collective effects, with unprecedented precision. Furthermore, together with HIJING simulations, this model is used to account for contributions from residual correlations induced by feed-down from particle decays. The extracted … |
