Classical Computation of Elliptic Flow at Large Transverse Momentum
  We compute the contribution of classical fields to the second Fourier coefficient (v_2) 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 v_2(p_t) at large transverse momentum p_t.
