This article reviews our current understanding of how the internal quark structure of a
nucleon bound in nuclei differs from that of a free nucleon. The interpretation of …

We review the spectrum and electromagnetic properties of baryons described as relativistic
three-quark bound states within QCD. The composite nature of baryons results in a rich …

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 …

The ratio of the proton's elastic electromagnetic form factors, GE p/GM p, was obtained by
measuring P t and P ℓ, the transverse and the longitudinal recoil proton polarization …

The ratio of the electric and magnetic form factors of the proton GE p/GM p, which is an
image of its charge and magnetization distributions, was measured at the Thomas Jefferson …

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 …

The ratio of the proton elastic electromagnetic form factors, G Ep/G Mp, was obtained by
measuring P t and P ℓ, the transverse and longitudinal recoil proton polarization …

We study minimal scenarios of resonant leptogenesis near the electroweak phase transition.
These models offer a number of testable phenomenological signatures for low-energy …

The Lagrangian that defines quantum chromodynamics (QCD), the strong interaction piece
of the Standard Model, appears very simple. Nevertheless, it is responsible for an …

We present measurements of the ratio of the proton elastic electromagnetic form factors, μ p
G Ep/G Mp. The Jefferson Lab Hall A Focal Plane Polarimeter was used to determine the …
