Calculations of a subatomic particle called the sigma provide insight into the communication between subatomic particles deep inside the heart of matter.
Researchers demonstrate a new technique for producing polarized positrons that could improve manufacturing and lead to new discoveries.
First mixed matter/anti-matter probe aims to solve decade-old proton puzzle.
The proton's primary building blocks, up and down quarks, are produced more often than strange quarks in scattering experiments.
First description of common particle’s properties provides insights into the nature of the universe.
New research could change our view of neutron stars and other systems with neutron-rich nuclei.
The recently upgraded CEBAF accelerator delivers its highest-energy electron beams into a new experimental complex for the first time.
