“…Even if to a lesser extent some information on the Boer-Mulders function [54] has been also gathered [55][56][57][58][59][60][61]. On the other hand, up to now, very little is known on gluon TMDs.…”

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].

“…In our practical calculations we assume that the scale dependences of 3dPDF and the spin averaged distribution function f 1 are the same. The same assumption has been applied in some extractions of 3dPDF [33,[47][48][49]. To what extent that this approximation is valid still needs to be studied.…”

“…As a result, they are less known than the chiral-even distribution functions. Anyway, there are some efforts to extract transversity from SIDIS data [46,47], and Boer-Mulders function from SIDIS and Drell-Yan data [48][49][50][51]. For h ⊥ 1T and h ⊥ 1L , there are extensive model calculations [52][53][54][55][56][57][58][59][60] and some proposals to measure them in SIDIS and pp Drell-Yan processes.…”

We study the azimuthal asymmetries in proton-proton Drell-Yan processes with one incident proton being transversely or longitudinally polarized. We consider particularly the asymmetries contributed by the leading-twist chiral-odd quark distributions. We analyze the asymmetries with sin(2φ + φS) and sin(2φ − φS) modulations in transverse single polarized p ↑ p Drell-Yan and sin 2φ asymmetries in longitudinal single polarized p → p Drell-Yan at the Relativistic Heavy Ion Collider, the Japan Proton Accelerator Research Complex, E906 (Fermi Lab), and the Nuclotron-based Ion Collider Facility (Joint Institute for Nuclear Research). We show that the measurements of the asymmetries in those facilities can provide valuable information of the chiral-odd structure of the nucleon both in the valence and sea regions.

“…It is also necessary to point out that the cos 2φ asymmetries may be explained by the twist-three quark-gluon correlations in collinear factorization [85], which is consistent with the Boer-Mulders effect in the TMD factorization approach in the intermediate energy scale Λ QCD Q T Q. A considerable volume of phenomenological work has been proposed to understand the cos 2φ asymmetry in an unpolarized Drell-Yan process based on the BoerMulders effect [32,37,44,56,[86][87][88][89][90][91][92][93][94][95][96][97][98][99][100][101][102][103]. Particularly, Boer [83] argued that it can account for the observed cos 2φ asymmetries observed in unpolarized πN Drell-Yan processes [70][71][72].…”

“…The data from nucleon-nucleon collision provide great opportunity to extract the BoerMulders function in the proton. Three different parameterizations [96,99,100] were adopted to fit those data to obtain the quark and antiquark Boer-Mulders function, based on the expressions for the cos 2φ asymmetries ν in pp and pD Drell-Yan processes:…”

This article presents a review of our present understanding of the spin structure of the unpolarized hadron. Particular attention is paid to the quark sector at leading twist, namely, the quark Boer-Mulders function, which describes the transverse polarization of the quark inside an unpolarized hadron. After introducing the operator definition of the Boer-Mulders function, a detailed treatment of different non-perturbative calculations of the Boer-Mulders functions is provided. The phenomenology in Drell-Yan processes and semi-inclusive leptoproduction, including the extraction of the quark and antiquark Boer-Mulders functions from experimental data, is presented comprehensively. Finally, prospects for future theoretical studies and experimental measurements are presented in brief.
