Semi-inclusive deep inelastic scattering at small transverse momentum
TL;DR: In this article, the cross section for one-particle inclusive deep inelastic scattering off the nucleon for low transverse momentum of the detected hadron was studied and the results were complete in the one-photon exchange approximation at leading and first sub-leading twist accuracy, with both beam and target polarization.
Journal ArticleDOI
Matches and mismatches in the descriptions of semi-inclusive processes at low and high transverse momentum
TL;DR: In this paper, the transverse-momentum dependence in semi-inclusive deep inelastic leptoproduction of hadrons was investigated, and two different theoretical approaches to study this dependence, one for low and one for high transverse momentum of the observed hadron were presented.

Azimuthal and single spin asymmetries in hard scattering processes
TL;DR: In this article, the authors review the present understanding of azimuthal and single spin asymmetries for particle production in unpolarized and polarized hadronic collisions at high energy and moderately large transverse momentum.

Generalized parton correlation functions for a spin-0 hadron
TL;DR: In this paper, the fully unintegrated, off-diagonal quark-quark correlator for a spin-1/2 hadron is parameterized in terms of generalized parton correlation functions.
Journal ArticleDOI
Dilepton production from polarized hadron hadron collisions
TL;DR: In this paper, a comprehensive formalism for dilepton production from the collision of two polarized spin-spin hadrons is presented by identifying the general angular distribution of the cross section in combination with a complete set of structure functions, which are computed in the parton model approximation where the transverse momentum of the dilepton pair is much smaller than its invariant mass.

Single-spin production asymmetries from the hard scattering of pointlike constituents.
TL;DR: This approach provides testable relationships between different asymmetries and represents the coherent spin-orbit forces in a polarized proton by defining an asymmetry in the transverse-momentum distribution of the fundamental constituents.

Parton Distribution and Decay Functions
John Collins,Davison E. Soper +1 more
TL;DR: In this paper, the authors define parton distribution and decay functions in QCD and prove some of their basic properties, such as renormalization, light-cone expansions and sum rules.

Leading-twist single-transverse-spin asymmetries: Drell–Yan and deep-inelastic scattering
TL;DR: In this paper, it was shown that the Sivers asymmetry vanishes due to the path-ordered exponential of the gluon field in the operator definition of parton densities.

Fragmentation of transversely polarized quarks probed in transverse momentum distributions
TL;DR: In this paper, it was shown that the azimuthal dependence of the distribution of hadrons in a quark jet is a probe of the transverse spin of the quark initiating the jet.

Time reversal odd distribution functions in leptoproduction
Daniël Boer,Piet J. Mulders +1 more
TL;DR: This work considers the various asymmetries, notably single spin asymmetry, that appear in leptoproduction as a consequence of the presence of time-reversal odd distribution functions, which could facilitate experimental searches for time-REVERSal odd phenomena.
