TL;DR: The CEBAF Large Acceptance Spectrometer (CLAS) as mentioned in this paper is used to study photo-and electro-induced nuclear and hadronic reactions by providing efficient detection of neutral and charged particles over a good fraction of the full solid angle.

TL;DR: A review of the physics motivation for dark sectors and the exciting opportunities for experimental exploration is provided in this article, where axions, which solve the strong CP problem and are an excellent dark matter candidate, and their generalization to axion-like particles.

TL;DR: In this paper, a search at the Jefferson Laboratory for new forces mediated by sub-GeV vector bosons with weak coupling α' to electrons was conducted using APEX test run data.

TL;DR: In this paper, the authors summarized the scientific importance of searches for dark sector dark matter and forces at masses beneath the weak scale, the status of this broad international field, the important milestones motivating future exploration, and promising experimental opportunities to reach these milestones over the next 5-10 years.

TL;DR: High-energy electron-scattering measurements show that even in heavy, neutron-rich nuclei, short-range interactions between the fermions form correlated high-momentum neutron-proton pairs, which has implications ranging from nuclear few-body systems to neutron stars and may also be observable experimentally in two-spin–state, ultracold atomic gas systems.
