Scientists predict that gluons, the particles that bind quarks, also bind to one another, but they have never unambiguously observed globs of pure ‘glue.’
Scientists track down coexistence of multiple shapes in the Nickel-64 nucleus: a spherical ground state and elongated and flattened shapes.
Tracking particles containing charm quarks offers insight into how quarks combine.
Physicists get closer to solving the proton radius puzzle with unique new measurement of the charge radius of the proton.
New measurements offer insights into binding interactions that glue fundamental building blocks of matter together.
Team combines many innovative accelerator accomplishments to keep gold ions cold and advance nuclear physics research.
Diagnostic test will improve performance of collider as physicists explore sources of proton spin
Low-momentum (wimpy) quarks and gluons contribute to proton spin, offering insights into protons’ behavior in all visible matter.
The spin direction of protons was reversed, for the first time, using a nine-magnet device, potentially helping tease out details about protons that affect medical imaging and more.
Antiquark spin contribution to proton spin depends on flavor, which could help unlock secrets about the nuclear structure of atoms that make up nearly all visible matter in our universe.
A precision measurement of the proton’s weak charge narrows the search for new physics.
Physicists develop a universal mathematical description that suggests that proton-neutron pairs in a nucleus may explain why their associated quarks have lower average momenta than predicted.
