Title: Small-x asymptotics of the gluon helicity distribution

Abstract

Here, we determine the small-x asymptotics of the gluon helicity distribution in a proton at leading order in perturbative QCD at large N _c. To achieve this, we begin by evaluating the dipole gluon helicity TMD at small x. In the process we obtain an interesting new result: in contrast to the unpolarized dipole gluon TMD case, the operator governing the small-x behavior of the dipole gluon helicity TMD is different from the operator corresponding to the polarized dipole scattering amplitude (used in our previous work to determine the small-x asymptotics of the quark helicity distribution).

The spin structure of the nucleon

Journal Article Deur, Alexandre ; Brodsky, Stanley J. ; de Téramond, Guy F. - Reports on Progress in Physics

We review the present understanding of the spin structure of protons and neutrons, the fundamental building blocks of nuclei collectively known as nucleons. The field of nucleon spin provides a critical window for testing Quantum Chromodynamics (QCD), the gauge theory of the strong interactions since it involves fundamental aspects of hadron structure, and it can be probed in detail in experiments, particularly deep inelastic lepton scattering on polarized targets. QCD was initially probed in high energy deep inelastic lepton scattering with unpolarized beams and targets. With time, interest shifted from testing perturbative QCD to illuminating the nucleon structure itself. Inmore »« less

Lattice QCD study of the Boer-Mulders effect in a pion

Journal Article Engelhardt, M. ; Hägler, P. ; Musch, B. ; ... - Physical Review D

The three-dimensional momenta of quarks inside a hadron are encoded in transverse momentumdependent parton distribution functions (TMDs). Our work presents an exploratory lattice QCD study of a TMD observable in the pion describing the Boer-Mulders effect, which is related to polarized quark transverse momentum in an unpolarized hadron. The primary goal is to gain insight into the behavior of TMDs as a function of a Collins-Soper evolution parameter,more »« less

Polarization phenomena in quantum chromodynamics

Conference Brodsky, S.J.

The author discusses a number of interrelated hadronic spin effects which test fundamental features of perturbative and non-perturbative QCD. For example, the anomalous magnetic moment of the proton and the axial coupling g{sub A} on the nucleon are shown to be related to each other for fixed proton radius, independent of the form of the underlying three-quark relativistic quark wavefunction. The renormalization scale and scheme ambiguities for the radiative corrections to the Bjorken sum rule for the polarized structure functions can be eliminated by using commensurate scale relations with other observables. Other examples include (a) new constraints on the shapemore »« less

Calculation of the QCD radiative corrections to helicity asymmetries in one-particle inclusive hadron processes

Thesis/Dissertation Karasinski, P.

Higher order QCD corrections to helicity asymmetries in high-p{perpendicular} one-particle inclusive hadron processes are analyzed in the framework of the parton model. First analytical expressions for {alpha}{sup 3} corrections to both helicity-averaged and helicity-dependent cross-sections for inclusive parton processes q{sub i}q{sub u} {yields} q{sub k}X, q{sub i}q{sub j} {yields} GX and q{sub i}q{sub j} {yields} q{sub k}X are obtained, where q{sub i} denotes quark with flavor i and G denotes a gluon. Next the corrections to helicity asymmetries for hadron processes resulting from these corrections are computed numerically.
