【 摘 要 】

The two-particle correlations at low relative momenta (correlation femtoscopy) are sensitive to quantum statistics and allow to measure the space-time picture of the system evolution created in lieavy-ion (HI) and particle collisions. The spatio-temporal parameters extracted from HI collisions describe the system at the last moment of the collision evolution - kinetic freeze-out. and provide the essential information about the formation of the quark-gluon plasma. The measurements at many facilities showed the dependencies of the spacial scales from the event multiplicity and particle transverse mass,mT.In this paper we show recent results obtained at RHIC and LHC energies and compare them to the theoretical expectations.
