Azimuthally differential pion femtoscopy in pb-pb collisions at = 2 tev

HIGHLIGHTS

• who: PRL and colleagues from the constantThe relative amplitudes of oscillations only weakly depend on kT, with the side-radii oscillation slightly increasing with kT . The final-state source eccentricity, estimated via side-radius oscillations, is noticeably smaller than at lower collisions energies, but still exhibits an out-ofplane elongated source at freeze-out even after a stronger in-plane expansion. The final eccentricity is slightly larger than that predicted by existing hydrodynamic calculations. The ALICE Collaboration would like to thank all its engineers and technicians for their invaluable contributions to the construction of the experiment and . . .
