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 …

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 …

Differential cross sections for the reaction γ p→ n π+ have been measured with the CEBAF
Large Acceptance Spectrometer (CLAS) and a tagged photon beam with energies from …

A dynamical coupled-channels (DCC) model for neutrino-nucleon reactions in the
resonance region is developed. Starting from the DCC model that we have previously …

We review the last two decades of using photon beams to measure the production of
mesons, and in particular the information that can be obtained on the spectrum of light, non …

Differential cross sections for the reaction γ p→ p π 0 have been measured with the CEBAF
Large Acceptance Spectrometer (CLAS) and a tagged photon beam with energies from …

A search for the Θ+ in the reaction γ d→ p K-K+ n was completed using the CLAS detector at
Jefferson Lab. A study of the same reaction, published earlier, reported the observation of a …

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 …

We have measured the nuclear transparency of the A (e, e′ π+) process in H 2, C 12, Al 27,
Cu 63, and Au 197 targets. These measurements were performed at the Jefferson …

We provide a perspective on studies aimed at observing the transition between hadronic
and quark–gluonic descriptions of reactions involving light nuclei. We begin by summarizing …
