The strong force which binds hadrons is described by the theory of quantum
chromodynamics (QCD). Determining the character and manifestations of QCD is one of the …

Precise proton and neutron form factor measurements at Jefferson Lab, using spin
observables, have recently made a significant contribution to the unraveling of the internal …

There has been much activity in the measurement of the elastic electromagnetic proton and
neutron form factors in the last decade, and the quality of the data has been greatly …

As the only stable baryon, the nucleon is of crucial importance in particle physics. Since the
nucleon is a building block for all atomic nuclei, there is a need to analyse the its structure in …

We discuss the links between generalized parton distributions (GPDs) and elastic nucleon
form factors. These links, in the form of sum rules, represent powerful constraints on …

We review the description of the lowest-energy nucleon excitation—the Δ (1232)-resonance.
Much of the recent experimental effort has been focused on the precision measurements of …

The aim of this report is to give basic notions on electromagnetic hadron form factors (FFs),
as they are understood at the present time, to summarize and analyze the present …

Theoretical as well as experimental progress has been made in the last decade in
describing the properties of baryons. In this review I will mostly report on the theoretical …

This article deals with the interplay between the properties of the neutron and its basic
interactions. Many of the neutron's properties underlie a simple quark model, and we …

Constraints from analyticity are combined with experimental electron-proton scattering data
to determine the proton charge radius. In contrast to previous determinations, we provide a …
