Relativistic heavy-ion collisions create a new state of hot hadronic matter which, as it expands and cools, undergoes a phase transition from deconfined to ordinary hadronic matter. By studying the correlations between identical particles produced by these collisions (pions in this case), one can unravel their spacetime evolution. The ALICE Collaboration finds qualitative agreement with certain specific predictions from hydrodynamic models regarding the hadronization scenario. The results show effects at the LHC that were not seen at the lower energies at RHIC, and present new trends in femtoscopy, the study of the dynamics of such very small, femtometer-size systems.
