We consider the inclusive production of hadrons in lepton-nucleon scattering. For a transversely polarized nucleon this reaction shows a left-right azimuthal asymmetry, which we compute in twist-3 collinear factorization at leading order in perturbation theory. All non-perturbative parton correlators of the calculation are fixed through information from other hard processes. Our results for the left-right asymmetry agree in sign with recent data for charged pion production from the HERMES Collaboration and from Jefferson Lab. However, the magnitude of the computed asymmetries tends to be larger than the data. Potential reasons for this outcome are identified. We also give predictions for future experiments and highlight in particular the unique opportunities at an Electron Ion Collider.

“…The cross section and double helicity asymmetry for η production is studied by PHENIX at midrapidity with comparison to π 0 production in Adare et al (2011a). The transverse single-spin asymmetry for forward η production looks as large as if not larger than that for forward π 0 production -see PHENIX (Adare et al, 2014) and STAR (Adamczyk et al, 2012) -and may be related to quark-gluon correlation functions.…”

We review the present understanding of η and η meson physics and these mesons as a probe of gluon dynamics in low-energy QCD. Recent highlights include the production mechanism of η and η mesons in proton-nucleon collisions from threshold to high-energy, the η effective mass shift in the nuclear medium, searches for possible η and η bound states in nuclei as well as precision measurements of η decays as a probe of light-quark masses. We discuss recent experimental data, theoretical interpretation of the different measurements and the open questions and challenges for future investigation.

“…However, due to the limited statistics precision and the narrow kinematic coverage of the SIDIS data, only the valence quark Sivers function at moderate to high x could be constrained in phenomenological fits [9]. The quark Sivers function has also been studied in polarized proton-proton collisions by the STAR and PHENIX collaborations at the Relativistic Heavy Ion Collider (RHIC) [10,11]. There are first indications both from STAR through the W -boson measurement [12] and COMPASS in Drell-Yan (DY) production [13] for the non-university of the Sivers function [5] if measured in hadron-hadron collisions or SIDIS, but the still challenging statistical precision limits a definite conclusion.…”

Accessing the gluon Sivers function at a future electron-ion collider

et al. 2018

In this work, we present a systematic study on the feasibility of probing the largely unexplored transverse momentum dependent gluon Sivers function (GSF) in open charm production, high pT charged di-hadron and di-jet production at a future high energy, high luminosity Electron-Ion Collider (EIC). The Sivers function is a measure for the anisotropy of the parton distributions in momentum space inside a transversely polarized nucleon. It is proposed that it can be studied through single spin asymmetries in the photon-gluon fusion subprocess in electron proton collisions at the EIC. Using a well tuned Monte Carlo model for deep inelastic scattering, we estimate the possible constraints of the GSF from the future EIC data. A comparison of all the accessible measurements illustrates that the di-jet channel is the most promising way to constrain the magnitude of the GSF over a wide kinematic range.
