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.
Pressure in the middle of a proton is about 10 times higher than in a neutron star.
Storing extremely slow neutrons in a novel trap enables precise measurement of a basic property of particle physics.
Yes. Such condensates, analogous to those in carbon-12, in heavier nuclei could change how we describe certain elements.
The MicroBooNE experiment demonstrates the use of machine learning to interpret images made by a liquid-argon particle detector.
New model provides more accurate estimates of how fast microbes produce a mercury-based neurotoxin.
First direct measurement show how heavy particles containing a charm quark get caught up in the flow of early universe particle soup.
Particle flow patterns suggest even small-scale collisions create drops of early universe quark-gluon plasma.
The first-ever computation of an atomic nucleus, the deuteron, on a quantum chip demonstrates that even today’s rudimentary quantum computers can solve nuclear physics questions.
Elegant techniques of trapping and polarizing atoms open vistas for beta-decay tests of fundamental symmetries, key to understanding the most basic forces and particles constituting our universe.
