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 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 …

Elastic πN scattering and the world data of the family of reactions π− p→ ηn, K 0 Λ, K 0 Σ 0,
K+ Σ−, and π+ p→ K+ Σ+ are described simultaneously in an analytic, unitary, coupled …

We develop a scheme for the extraction of the properties of the scalar mesons f 0 (600), f 0
(980), and a 0 (980) from lattice QCD data. This scheme is based on a two-channel chiral …

The topical workshop Strong QCD from Hadron Structure Experiments took place at
Jefferson Lab from November 6–9, 2019. Impressive progress in relating hadron structure …

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 …

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 …

Accessing a full image of the inner content of hadrons represents a central endeavour of
modern particle physics, with the main scientific motivation to investigate the strong …

The reactions γp→π^0p and γp→π^+n are analyzed in a semi-phenomenological approach
up to E∼2.3 GeV. Fits to differential cross section and single-and double-polarization …
