Classical computation of elliptic flow at large transverse momentum

摘要

We compute the contribution of classical fields to the second Fourier coefficient (nu(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 nu(2)(p(t)) at large transverse momentum pt. (C) 2002 Elsevier Science B.V.
