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…
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…
