摘要：
We discuss the azimuthal asymmetries of the Drell-Yan process in nucleon-nucleus collisions at the low transverse momentum of the lepton pair. Within the transverse-momentum-dependent (TMD) factorization formalism, the nuclear effects of these azimuthal asymmetries can be from the gauge link of the TMD quark distribution. We estimate all these nuclear effects within the assumption that all the TMD parton distributions or correlations are in Gaussian forms.
