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 …

During its long-lasting history, the Λ (1405) has become a benchmark for our understanding
of the SU (3) hadron dynamics. Starting with its theoretical prediction and later experimental …

A chiral unitary approach for antikaon-nucleon scattering in on-shell factorization is studied.
We find multiple sets of parameters for which the model describes all existing hadronic data …

This review treats the advances in Light Baryon Spectroscopy of the last two decades, which
were mainly obtained by measuring meson-production reactions at photon facilities all over …

The ηN final state is isospin-selective and thus provides access to the spectrum of excited
nucleons without being affected by excited Δ states. To this end, the world database on eta …

We present a determination of the P-wave π π→ π γ⋆ transition amplitude from lattice
quantum chromodynamics. Matrix elements of the vector current in a finite volume are …

Advances in the exploration of the spectrum and structure of the excited states of the
nucleon from experiments with electromagnetic probes on proton targets are presented …

The Jülich-Bonn dynamical coupled-channel approach is extended to include K Σ
photoproduction off the proton. Differential cross section and (double) polarization data for …

Masses, widths, and branching ratios of hadronic resonances are quantified by their pole
positions and residues with respect to transition amplitudes on the Riemann sheets of the …

The weak decay parameter α-of the Λ is an important quantity for the extraction of
polarization observables in various experiments. Moreover, in combination with α+ from Λ¯ …
