| English abstract | Using recent high-statistics STAR data from Au+Au and Cu+Cu collisions at full RHIC energy I discuss strong and Coulomb-induced final state interaction effects on identical (π−π) and non-identical (π−Ξ) particle correlations. Analysis of π−Ξ correlations reveals the strong and Coulomb-induced FSI effects, allowing for the first time to estimate spatial extension of π and Ξ sources and the average shift between them. Source imaging techniques provide clean separation of details of the source function and are applied to the one-dimensional relative momentum correlation function of identical pions. For low momentum pions, and/or non-central collisions, a large departure from a single-Gaussian shape is observed |
