Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary ...

LAWRENCE -- A team of high-energy nuclear experimental particle physicists from the University of Kansas has earned a two-year, $400,000 Department of Energy (DoE) grant to investigate strong ...

Inside the most powerful particle colliders on Earth, protons slam together at nearly the speed of light, shredding matter ...

For the first time, by studying quantum correlations between triplets of secondary particles created during high-energy collisions in the LHC accelerator, it has been possible to observe their ...

Comparing the number of direct photons emitted when proton spins point in opposite directions (top) with the number emitted when protons collide head-to-tail (bottom) revealed that gluon spins align ...

Holographic QCD employs ideas drawn from string theory and the AdS/CFT correspondence to study the strong coupling regime of quantum chromodynamics, offering a dual gravitational description of quark ...

The early Universe was a strange place. The Universe was so dense and hot that atoms and nuclei could not form—they would be ripped apart by high-energy collisions. Even protons and neutrons could not ...

Scientists seeking to explore the teeming microcosm of quarks and gluons inside protons and neutrons report new data delivered by particles of light. The light particles, or photons, come directly ...

A team of physicists has embarked on a journey where few others have gone: into the glue that binds atomic nuclei. The resultant measurement, which was extracted from experimental data taken at the ...

In the first fractions of a second of our Universe's existence, the energy density was so incredibly high that there were no protons and neutrons, just a hot "quark soup" known as a quark-gluon plasma ...

Quarks are elemental particles, with no sub-structure. Understanding them is crucial to learning how physics works on the smallest levels. By studying collisions of incredibly small particles made up ...
