How gauge covariance of the fermion and boson propagators in QED constrain the effective fermion-boson vertex
Shaoyang Jia, M. R. Pennington
We derive the gauge covariance requirement imposed on the QED fermion-photon three-point function within the framework of a spectral representation for fermion propagators. When sa…
Landau-Khalatnikov-Fradkin transformation for the fermion propagator in QED in arbitrary dimensions
Shaoyang Jia, M. R. Pennington
We explore the dependence of fermion propagators on the covariant gauge fixing parameter in quantum electrodynamics (QED) with the number of spacetime dimensions kept explicit. Gau…
Gauge covariance of the fermion Schwinger-Dyson equation in QED
Shaoyang Jia, M. R. Pennington
Any practical application of the Schwinger-Dyson equations to the study of -point Green's functions of a field theory requires truncations, the best known being finite order per…
Workshop on Physics with Neutral Kaon Beam at JLab (KL2016) Mini-Proceedings
M. Albrow, M. Amaryan, E. Chudakov +34
The KL2016 Workshop is following the Letter of Intent LoI12-15-001 "Physics Opportunities with Secondary KL beam at JLab" submitted to PAC43 with the main focus on the physics of e…
Evolving images of the proton: Hadron physics over the past 40 years
Michael R. Pennington
Once upon a time, the world was simple: the proton contained three quarks, two {\it ups} and a {\it down}. How these give the proton its mass and its spin seemed obvious. Over the…
