Quantum Monte Carlo methods have proved valuable to study the structure and reactions of
light nuclei and nucleonic matter starting from realistic nuclear interactions and currents …

We describe the research and development work for the P2 experiment which aims for a
high precision determination of the weak mixing angle \sin^2W sin 2 θ W to a precision of …

The recent experimental determination of the parity violating asymmetry A PV in Ca 48 and
Pb 208 at Jefferson Lab is important for our understanding on how neutrons and protons …

We report the first measurement of the parity-violating asymmetry A PV in the elastic
scattering of polarized electrons from Pb 208. A PV is sensitive to the radius of the neutron …

The parity-violating asymmetry A PV in Pb 208, recently measured by the PREX-2
Collaboration, is studied using modern relativistic (covariant) and nonrelativistic energy …

Large experimental programmes in the fields of nuclear and particle physics search for
evidence of physics beyond that explained by current theories. The observation of the Higgs …

The symmetry energy describes how the energy of nuclear matter rises as one goes away
from equal numbers of neutrons and protons. This is very important to describe neutron rich …

A model-independent analysis of the infinite-momentum-frame charge density of partons in
the transverse plane is presented for the nucleon. We find that the neutron-parton charge …

Experiments with cold and ultracold neutrons have reached a level of precision such that
problems far beyond the scale of the present standard model of particle physics become …

As a follow up of our work on the electromagnetic four-current, we study for the first time the
relativistic polarization and magnetization spatial distributions inside a spin-1 2 target within …
