Quantum Chromodynamics, the theory of quarks and gluons, whose interactions can be
described by a local SU (3) gauge symmetry with charges called “color quantum numbers” …

The last decade has seen a marked shift in how the internal structure of hadrons is
understood. Modern experimental facilities, new theoretical techniques for the continuum …

The last five years have brought considerable progress in the study of the bound-state
problem in continuum quantum field theory. We highlight a subset of that progress; viz., that …

The composite nature of baryons manifests itself in the existence of a rich spectrum of
excited states, in particular in the important mass region 1–2 GeV for the light-flavoured …

Studies of the structure of excited baryons are key factors to the N* program at Jefferson Lab
(JLab). Within the first year of data taking with the Hall B CLAS12 detector following the 12 …

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 …

Understanding the strong interaction dynamics that govern the emergence of hadron mass
(EHM) represents a challenging open problem in the Standard Model. In this paper we …

Recent experimental and theoretical advancements have led to significant progress in our
understanding of the electromagnetic structure of nucleons (N), nucleon excitations (N∗) …

We present a unified study of nucleon and\({\Delta}\) elastic and transition form factors, and
compare predictions made using a framework built upon a Faddeev equation kernel and …

A resonancelike structure, the P c (4450), has recently been observed in the J/ψ p spectrum
by the LHCb Collaboration. We discuss the feasibility of detecting this structure in J/ψ …
