Aspects of Hadron Physics
C. D. Roberts, M. S. Bhagwat, S. V. Wright +1
Detailed investigations of the structure of hadrons are essential for understanding how matter is constructed from the quarks and gluons of Quantum chromodynamics (QCD), and amongs…
Schwinger functions and light-quark bound states
M. S. Bhagwat, A. Hoell, A. Krassnigg +2
We examine the applicability and viability of methods to obtain knowledge about bound-states from information provided solely in Euclidean space. Rudimentary methods can be adequat…
A Perspective on Hadron Physics
Arne Hoell, Craig D. Roberts, Stewart V. Wright
The phenomena of confinement and dynamical chiral symmetry breaking are basic to understanding hadron observables. They can be explored using Dyson-Schwinger equations. The existen…
Electromagnetic properties of ground and excited state pseudoscalar mesons
A. Hoell, A. Krassnigg, P. Maris +2
The axial-vector Ward-Takahashi identity places constraints on particular properties of every pseudoscalar meson. For example, in the chiral limit all pseudoscalar mesons, except t…
On Nucleon Electromagnetic Form Factors
R. Alkofer, A. Hoell, M. Kloker +2
A Poincare' covariant Faddeev equation, which describes baryons as composites of confined-quarks and -nonpointlike-diquarks, is solved to obtain masses and Faddeev amplitudes for t…
Confinement, DCSB, Bound States, and the Quark-Gluon Vertex
A. Holl, A. Krassnigg, C. D. Roberts
Aspects of the dressed-quark-gluon vertex and their role in the gap and Bethe-Salpeter equations are briefly surveyed using an intuitive model. The model allows one to elucidate wh…
Aspects and consequences of a dressed-quark-gluon vertex
M. S. Bhagwat, A. Hoell, A. Krassnigg +2
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 ne…
Mean field exponents and small quark masses
Arne Hoell, Pieter Maris, Craig D. Roberts
We demonstrate that the restoration of chiral symmetry at finite-T in a class of confining Dyson-Schwinger equation (DSE) models of QCD is a mean field transition, and that an accu…
