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…

Existence and stability of multiple solutions to the gap equation

Kun-lun Wang, Si-xue Qin, Yu-xin Liu +3

We argue by way of examples that, as a nonlinear integral equation, the gap equation can and does possess many physically distinct solutions for the dressed-quark propagator. The e…

Dressed-quarks and the nucleon's axial charge

Lei Chang, Craig D. Roberts, Sebastian M. Schmidt

The nucleon's axial charge, g_A, expresses features that are both fundamental to the strong interaction and crucial to its connection with weak interaction physics. We show that dy…

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…

Hadron physics and dynamical chiral symmetry breaking

Lei Chang, Craig D. Roberts, David J. Wilson

Physics is an experimental science; and a constructive feedback between theory and extant and forthcoming experiments is necessary if an understanding of nonperturbative QCD is to…

Nucleon and Roper electromagnetic elastic and transition form factors

D. J. Wilson, I. C. Cloet, L. Chang +1

We compute nucleon and Roper e.m. elastic and transition form factors using a symmetry-preserving treatment of a contact-interaction. Obtained thereby, the e.m. interactions of bar…
