Abstract:In this paper we probe the Sivers asymmetries through J/psi photoproduction in (p)up arrow(p) collision within the nonrelativistic QCD framework, based on the color-octet model and the transverse-momentum-dependent parton distributions (TMDs). Both the Dokshitzer-Gribov-Lipatov-Altarelli-Parisi evolution and TMD evolution are included. The intensity and sign of the Sivers asymmetry are strongly dependent upon the evolution model used to investigate the gluon Sivers function (GSF). Sizable asymmetries are obtained as a function of the rapidity, log(x(gamma)), or log(x(g)) using a recent parametrization of the GSF at the RHIC and AFTER@LHC experiments with the planned LHC forward-detector acceptances.
