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 …

About 120 baryons and baryon resonances are known, from the abundant nucleon with u
and d light-quark constituents up to the Ξ b−=(bsd), which contains one quark of each …

The vast majority of hadrons observed in nature are not stable under the strong interaction;
rather they are resonances whose existence is deduced from enhancements in the energy …

We review recent progress in the investigation of the electroexcitation of nucleon
resonances, both in experiment and in theory. We describe current experimental facilities …

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 …
