Abstract

We compute the contribution of classical fields to the second Fourier coefficient (v₂) of the azimuthal gluon distribution at large transverse momentum in heavy ion collisions. We find that the classical contribution to the flow alone cannot account for the experimentally observed behavior of v₂(p_t) at large transverse momentum p_t.
