Structure of the nucleon's low-lying excitations
Chen Chen, Bruno El-Bennich, Craig D. Roberts +3
A continuum approach to the three valence-quark bound-state problem in quantum field theory is used to perform a comparative study of the four lightest bary…
Valence-quark distribution functions in the kaon and pion
Chen Chen, Lei Chang, Craig D. Roberts +2
We describe expressions for pion and kaon dressed-quark distribution functions that incorporate contributions from gluons which bind quarks into these mesons and hence overcome a f…
Elastic and transition form factors of the Δ(1232)
Jorge Segovia, Chen Chen, Ian C. Cloët +3
Predictions obtained with a confining, symmetry-preserving treatment of a vector-vector contact interaction at leading-order in a widely used truncation of QCD's Dyson-Schwinger eq…
Insights into the gamma* N -> Delta transition
Jorge Segovia, Chen Chen, Craig D. Roberts +1
The γ* N -> Δ(1232) transition is a window on hadron shape deformation, the applicability of perturbative QCD at moderate momentum transfers, and the influence of nonperturbative p…
Features and flaws of a contact interaction treatment of the kaon
Chen Chen, Lei Chang, Craig D. Roberts +3
Elastic and semileptonic transition form factors for the kaon and pion are calculated using the leading-order in a global-symmetry-preserving truncation of the Dyson-Schwinger equa…
Spectrum of hadrons with strangeness
Chen Chen, Lei Chang, Craig D. Roberts +2
We describe a calculation of the spectrum of strange and nonstrange hadrons that simultaneously correlates the dressed-quark-core masses of meson and baryon ground- and excited-sta…
