DOI: 10.1103/physrevd.99.014003
Abstract: We study the production of prompt-photons at RHIC with a view to obtain information on the gluon Sivers function (GSF). At RHIC energy ($\sqrt{s}=200$ GeV), the Compton process, $gq\to\gamma q$ contributes significantly to the production… read more here.

DOI: 10.1142/s0217751x17501767
Abstract: Sivers effect is describing the correlation between the transverse polarization of nucleon and the transverse momentum, k⊥, of its unpolarized constituent partons. This effect is an outstanding subject and in this regard, a great deal… read more here.
