Researchers imaged individual barium ions in dense xenon gas, offering a new path toward ultra-low-background searches for neutrinoless double beta decay.

Calculations of charge distribution in mesons provide a benchmark for experimental measurements and validate widely used 'factorization' method.

Precise measurement of beryllium-7 nuclear decay recoils directly probes the quantum properties of the neutrino for the first time.

First precise measurement of a hard to detect bound charm quark pair state indicates it is not affected by the medium in high-energy proton-lead collisions.

Particles of light from collisions of deuterons with gold ions provide direct evidence that energetic jets get stuck.

Theoretical calculations suggest charm tetraquarks may be less compact than previously thought.

Successfully modeling chromium-62 hints at an interesting structure for neutron-laden calcium-60.

Theorists show gluon fields characterizing gluon saturation can describe a universal pattern of particle emissions—a manifestation of asymptotic symmetry.

Scientists gain new insights into the nature of the puzzling lambda 1405 hyperon resonance and its controversial partner.

Data show the distribution of gluon “glue” in protons and neutrons changes when they are bound together in nuclei.
