“…the valence quark Sivers distributions, at not too small Bjorken-x values (x ∼ 1/N c ) (see ref. [63] and references therein). The COMPASS Collaboration at CERN is currently studying the Sivers asymmetry in the production of high-p T hadron pairs in muon scattering off polarized proton and deuteron targets [64].…”

Within a generalized parton model approach, with inclusion of spin and intrinsic transverse momentum effects, we show how the latest, highly precise, midrapidity data on the transverse single spin asymmetry measured in pp → π 0 X by the PHENIX Collaboration at RHIC [1], can be used to get a first estimate on the still poorly known gluon Sivers distribution. To this end we also adopt the present information on the quark Sivers functions, as extracted from semi-inclusive deeply inelastic scattering data. This analysis updates a previous study by some of us where a first bound on this distribution was obtained [2].

“…Let us also mention that in Ref. [238] the BSR, together with the large N c limit of QCD, was used to predict a suppression of the gluon Sivers function w.r.t. the non-singlet quark Sivers distribution at not too small x.…”

In this article we review the present understanding of azimuthal and single spin asymmetries for inclusive and semi-inclusive particle production in unpolarized and polarized hadronic collisions at high energy and moderately large transverse momentum. After summarizing the experimental information available, we discuss and compare the main theoretical approaches formulated in the framework of perturbative QCD. We then present in some detail a generalization of the parton model with inclusion of spin and intrinsic transverse momentum effects. In this context, we extensively discuss the phenomenology of azimuthal and single spin asymmetries for several processes in different kinematical configurations. A comparison with the predictions of other approaches, when available, is also given. We finally emphasize some relevant open points and challenges for future theoretical and experimental investigation.

“…Experimentally f ⊥ 1T can be studied, e.g., by measuring a transverse SSA in semi-inclusive deep-inelastic scattering (SIDIS). Extractions of the Sivers function from existing SIDIS data [11,12,16,18] have already been performed [29,30,31,32,33,34].…”

Relations between generalized and transverse momentum dependent parton distributions

Recent work suggests nontrivial relations between generalized parton distributions on the one hand and (naive time-reversal odd) transverse momentum dependent distributions on the other. Here we review the present knowledge on such type of relations. Moreover, as far as spectator model calculations are concerned, the existing results are considerably extended. While various relations between the two types of parton distributions can be found in the framework of spectator models, so far no nontrivial model-independent relations have been established.
