The infrared behaviour of QCD Green's functions: confinement, dynamical symmetry breaking, and hadrons as relativistic bound states

R Alkofer, L Von Smekal - Physics Reports, 2001 - Elsevier
Recent studies of QCD Green's functions and their applications in hadronic physics are
reviewed. We discuss the definition of the generating functional in gauge theories, in …

Dyson–Schwinger equations: a tool for hadron physics

P Maris, CD Roberts - International Journal of Modern Physics E, 2003 - World Scientific
Dyson–Schwinger equations furnish a Poincaré covariant framework within which to study
hadrons. A particular feature is the existence of a nonperturbative, symmetry preserving …

Distribution functions of the nucleon and pion in the valence region

RJ Holt, CD Roberts - arXiv preprint arXiv:1002.4666, 2010 - arxiv.org
We provide an experimental and theoretical perspective on the behavior of unpolarized
distribution functions for the nucleon and pion on the valence-quark domain; namely …

Cross section and complete set of proton spin observables in elastic scattering at 250 MeV

K Hatanaka, Y Shimizu, D Hirooka, J Kamiya… - Physical Review C, 2002 - APS
The angular distributions of the cross section, the proton analyzing power, and all proton
polarization transfer coefficients of p→ d elastic scattering were measured at 250 MeV. The …

The stability of nuclear matter in the Nambu–Jona-Lasinio model

W Bentz, AW Thomas - Nuclear Physics A, 2001 - Elsevier
Using the Nambu–Jona-Lasinio model to describe the nucleon as a quark–diquark state, we
discuss the stability of nuclear matter in a hybrid model for the ground state at finite nucleon …

Aspects and consequences of a dressed-quark-gluon vertex

MS Bhagwat, A Höll, A Krassnigg, CD Roberts… - Physical Review C …, 2004 - APS
Features of the dressed-quark-gluon vertex and their role in the gap and Bethe-Salpeter
equations are explored. It is argued that quenched lattice data indicate the existence of net …

Bethe-Salpeter equation and a nonperturbative quark-gluon vertex

A Bender, W Detmold, AW Thomas, CD Roberts - Physical Review C, 2002 - APS
A Ward-Takahashi identity preserving Bethe-Salpeter kernel can always be calculated
explicitly from a dressed-quark-gluon vertex whose diagrammatic content is enumerable …

Effective masses of diquarks

P Maris - Few-Body Systems, 2002 - Springer
We study meson and diquark bound states using the rainbow-ladder truncation of QCD's
Dyson-Schwinger equations. The infrared strength of the rainbow-ladder kernel is described …

Transverse-momentum-dependent fragmentation and quark distribution<? format?> functions from the Nambu–Jona-Lasinio–jet model

HH Matevosyan, W Bentz, IC Cloët, AW Thomas - Physical Review D …, 2012 - APS
Using the model of Nambu and Jona-Lasinio to provide a microscopic description of both
the structure of the nucleon and of the quark to hadron elementary fragmentation functions …

Role of diquark correlations and the pion cloud in nucleon elastic form factors

IC Cloët, W Bentz, AW Thomas - Physical Review C, 2014 - APS
Electromagnetic form factors of the nucleon in the spacelike region are investigated within
the framework of a covariant and confining Nambu–Jona-Lasinio model. The bound-state …
