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 …

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

Elastic πN scattering and the reaction π+ p→ K+ Σ+ are described simultaneously in a
unitary coupled-channels approach which respects analyticity. SU (3) flavor symmetry is …

The Δ (1232)→ γ* N magnetic dipole form factor (GM*) is described here within a new
covariant model that combines the valence quark core together with the pion cloud …

We extend a covariant model, tested before in the spacelike region for the physical and
lattice QCD regimes, to a calculation of the γ* N→ Δ reaction in the timelike region, where …

The covariant spectator quark model, tested before in a variety of electromagnetic baryon
excitations, is applied here to the γ* N→ N*(1520) reaction in the timelike regime. The …

A relativistic constituent quark model is applied to the γ N→ N (1535) transition. The N
(1535) wave function is determined by extending the covariant spectator quark model …

We study the octet baryon electromagnetic properties by applying the covariant spectator
quark model, and provide covariant parametrization that can be used to study baryon …

We study the octet to decuplet baryon electromagnetic transitions using the covariant
spectator quark model and predict the transition magnetic dipole form factors for those …
