Abstract
First measurements of the azimuthal anisotropy of neutral pions produced in Pb-Pb collisions at a center-of-mass energy of [√ over s[subscript NN]]=2.76 TeV are presented. The amplitudes of the second Fourier component (v[subscript 2]) of the π[superscript 0] azimuthal distributions are extracted using an event-plane technique. The values of v[subscript 2] are studied as a function of the neutral pion transverse momentum (p[subscript T]) for different classes of collision centrality in the kinematic range 1.6
