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 duality between partonic and hadronic descriptions of physical phenomena is one of the
most remarkable features of strong interaction physics. A classic example of this is in …

We review a unique prediction of Quantum Chromo Dynamics, called color transparency
(CT), where the final (and/or initial) state interactions of hadrons with the nuclear medium …

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 …

The incoherent pion photoproduction reaction γ d→ π− pp is considered theoretically in a
wide energy region E th≤ E γ≤ 2700 MeV. The model applied contains the impulse …

A review of our works providing a theoretical description of incoherent pion photoproduction
on the deuteron is presented. The existing γ d→ π NN data are analysed, especially those …

Exclusive photoproduction cross sections have been measured for the process γ p→ p π 0
[e+ e−(γ)] with the Dalitz decay final state using tagged photon energies in the range of E γ …

The differential cross sections for the γ n→ π-p and the γ p→ π+ n processes were
measured at Jefferson Lab. The photon energies ranged from 1.1 to 5.5 GeV, corresponding …

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 …

We propose to use hard exclusive production of an exotic hadron for finding its internal
quark-gluon configuration by the constituent-counting rule in perturbative QCD. In particular …
