The Electron-Ion Collider (EIC) is a facility being constructed at Brookhaven National Lab that will enable investigation of gluon interactions and structure in nucleons and nuclei using polarized beams of electrons and atomic nuclei. The Electron-Proton/Ion Collider (ePIC) experiment will be the first to run at EIC. The ePIC detector will be a barrel-shaped hermetic detector comprised of...
One of the most challenging goals in modern physics is to understand hadronic structure, as properties of constituent quarks and gluons (e.g. spin, mass) do not explicitly add up to the properties of hadrons. The pion ($\pi$-meson) is the lightest quark system and its properties are deeply linked to the understanding of how quarks are confined in hadronic matter. The pion form factor...
Despite being a core component of visible matter, the structure of protons and neutrons is still incompletely understood. Due to the limitations of QCD in the non-perturbative regime, hadronic structure must be determined via experiment. The KaonLT experiment at Jefferson Lab Hall C measures Deep Exclusive Meson Production (DEMP) reactions in order to study the interior structure of the proton...
Precise measurements of the neutron electric dipole moment (EDM) could result in a discovery of a violation of particle-antiparticle symmetry, and of new physics beyond the standard model.
The TRIUMF Ultracold Advanced Neutron (TUCAN) collaboration is preparing an experiment to measure the neutron EDM with an accuracy of $1\times10^{-27}$~$e$cm, a factor of 10 better than the world's previous...
One of the fundamental objectives of hadron physics is to explore how quark and gluon interactions shape the hadron spectrum as described by Quantum Chromodynamics (QCD). The GlueX experiment at Jefferson Lab plays a key role in this global spectroscopy program by utilizing an 8–9 GeV beam of linearly polarized photons to investigate meson production. By focusing on the light-quark sector,...
The internal structure of hadrons is incompletely understood, as the intrinsic properties of hadrons (e.g. mass, spin) cannot yet be fully understood within a QCD framework. Generalized Parton Distributions (GPDs) provide information about the three dimensional structure of hadrons. The pion is a good candidate for hadron structure studies, due to its relatively simple structure and its...
