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…
Electric dipole moment of the rho-meson
Mario Pitschmann, Chien-Yeah Seng, Michael J. Ramsey-Musolf +3
At an hadronic scale the effect of CP-violating interactions that typically appear in extensions of the Standard Model may be described by an effective Lagrangian, in which the ope…
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…
