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

Recent experimental and theoretical advances in investigating electromagnetic meson
production reactions in the nucleon resonance region are reviewed. We give a description of …

High-statistics cross sections for the reactions γ+ p→ K++ Λ and γ+ p→ K++ Σ 0 have been
measured using CLAS at Jefferson Lab for center-of-mass energies W between 1.6 and 2.53 …

The reactions γp→K^+Λ and γp→K^+Σ^0 were measured in the energy range from
threshold up to a photon energy of 2.6 GeV. The data were taken with the SAPHIR detector …

Spin transfer from circularly polarized real photons to recoiling hyperons has been
measured for the reactions γ→+ p→ K++ Λ→ and γ→+ p→ K++ Σ→ 0. The data were …

Differential cross sections and photon-beam asymmetries for the γ→ p→ K+ Λ and γ→ p→
K+ Σ 0 reactions have been measured in the photon energy range from 1.5 to 2.4 GeV and …

High-statistics cross sections and recoil polarizations for the reactions γ+ p→ K++ Λ and γ+
p→ K++ Σ 0 have been measured at CLAS for center-of-mass energies between 1.6 and 2.3 …

Experiments using proton beams at high luminosity colliders and fixed target facilities
provide impressive sensitivity to new light weakly coupled degrees of freedom. With these …

We present a nucleon resonance analysis by simultaneously considering all pion-and
photon-induced experimental data on the final states γ N, π N, 2 π N, η N, K Λ, K Σ, and ω N …

Beam asymmetries and hyperon recoil polarizations for the reactions γ p→ K+ Λ and γ p→
K+ Σ 0 have been measured from the threshold production to 1500MeV with the GRAAL …
