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 …

10.1140/epja/i2012-12015-8 Regular Article – Theoretical Physics Eur. Phys. J. A (2012) 48: 15 …

The nucleon resonances are investigated within a dynamical coupled-channels model of π
N and γ N reactions up to the invariant mass W= 2 GeV. The meson-baryon (MB) channels …

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

We report on a high-statistics measurement of the basic double pionic fusion reaction $ pn\to
d\pi^ 0\pi^ 0$ over the energy region of the so-called ABC effect, a pronounced low-mass …

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

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 …

Exclusive measurements of the quasi-free np→ np π 0 π 0 reaction have been performed by
means of dp collisions at T d= 2.27 GeV using the WASA detector setup at COSY. Total and …

The photoproduction of 2 π 0 mesons off protons was studied with the Crystal Barrel/TAPS
experiment at the electron accelerator ELSA in Bonn. The energy of photons produced in a …
