Аннотация:Femtoscopy allows one to measure the space-time characteristics of particle production using correlations resulting from the effects of quantum statistics and final state interactions. We present the results of femtoscopic analyses for different two-particle systems measured by ALICE in Pb-Pb, p-Pb and pp collisions, pointing out the similarities and differences between small and large systems. Results for kaons provide a cross-check of the information about the dynamics of the source and the importance of the hadronic rescattering phase. The recent femtoscopic results for baryon-(anti-)baryon pairs and kaon pairs allow one to study the strong interaction parameters and cross-sections.
