We consider the leading and sub-leading twist T-odd and even contributions to the cos 2{phi} azimuthal asymmetry in unpolarized dilepton production in Drell-Yan Scattering We estimate the contributions' effects at 500 GeV, 50 GeV, and 25 GeV energies in the framework of the parton model using a quark diquark-spectator model of the nucleon to approximate the soft contributions.
