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 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 …

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 …

Parity violating electron nucleus scattering is a clean and powerful tool for measuring the
spatial distributions of neutrons in nuclei with unprecedented accuracy. Parity violation …

▪ Abstract The Jefferson Laboratory's superconducting radiofrequency (srf) Continuous
Electron Beam Accelerator Facility (CEBAF) provides multi-GeV continuous-wave (cw) …

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 …

We report a new, high-precision measurement of the proton elastic form factor ratio
μpGE/GM for the four-momentum transfer squared Q2= 0.3–0.7 (GeV/c) 2. The measurement …

Weak magnetism increases antineutrino mean free paths in core collapse supernovae. The
parity violating interference between axial vector and vector currents makes antineutrino …

We have measured the parity-violating electroweak asymmetry in the elastic scattering of
polarized electrons from protons. Significant contributions to this asymmetry could arise from …

We report a new determination of the strange quark contribution to the proton's magnetic
form factor at a four-momentum transfer Q2= 0.1 (GeV/c) 2 from parity-violating e–p elastic …
