Centrality dependence of pion freeze-out radii in Pb-Pb collisions at $\sqrt{{\mathbf{s}}_{\mathbf{NN}}}$=2.76 TeV

ALICE Collaboration

We report on the measurement of freeze-out radii for pairs of identical-charge pions measured in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}}=2.76$ TeV as a function of collision centra…
