We review the spectrum and electromagnetic properties of baryons described as relativistic
three-quark bound states within QCD. The composite nature of baryons results in a rich …

Quantum chromodynamics (QCDs) is the strongly interacting part of the Standard Model. It is
supposed to describe all of nuclear physics; and yet, almost 50 years after the discovery of …

Discovered in 1963, the Roper resonance appears to be an exact copy of the proton except
that its mass is 50% greater and it is unstable. These features of the Roper have been very …

We employ a continuum approach to the three valence-quark bound-state problem in
relativistic quantum field theory to predict a range of properties of the proton's radial …

In principle, the strong-interaction sector of the standard model is characterized by a unique
renormalization-group-invariant (RGI) running interaction and a unique form for the dressed …

Ward-Green-Takahashi (WGT) identities play a crucial role in hadron physics, eg imposing
stringent relationships between the kernels of the one-and two-body problems, which must …

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 (I= 1/2, JP= 1/2±) baryon …

Given the unique role played by the gravitational form factors (GFFs) in unraveling the
internal mechanics of hadrons, we examine the GFFs of ground state pseudoscalar mesons …

We extract the leading Fock-state light front wave functions of heavy flavor-asymmetric
pseudoscalar mesons D, B, and B c from their Bethe-Salpeter wave functions, based on the …

We compute all kaon and pion parton distribution amplitudes (PDAs) to twist three and find
that only the pseudotensor PDA can reasonably be approximated by its conformal limit …
