Correlation femtoscopy of multiparticle processes

Abstract

Recent results on particle momentum and spin correlations are discussed in view of the role played by the effects of quantum statistics, including multiboson and coherence phenomena, and final state interaction. Particularly, it is demonstrated that the latter allows for (i) correlation femtoscopy with unlike particles; (ii) study of the relative space--time asymmetries in the production of different particle species (e.g., relative time delays or spatial shifts due to collective flows); (iii) study of the particle strong interaction hardly accessible by other means (e.g., in two-lambda system).
