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 ...

Polarized proton containing spinning quarks and gluons (represented by right-handed and left-handed spirals). The negative Δg solutions (blue) are disfavored relative to the positive Δg solutions (red ...

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons. The temporary pair of correlated ...

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 ...

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 ...

Theorists have calculated how quickly a melted soup of quarks and gluons -- the building blocks of protons and neutrons -- transfers its momentum to heavy quarks. The calculation will help explain ...

All the matter we know of in the Universe is made up of Standard Model particles. Photons and neutrinos zip through the Universe all the time, far outnumbering all the other particles. Normal, ...

A cartoon of the quark-gluon plasma (small red, green, and blue circles) produced in a relativistic heavy ion collision between two heavy nuclei (white circles). The collision produces a heavy quark ...

The detection is detailed in a new study published in the journal Physical Review Letters. Immediately following the Big Bang, the universe was an extremely hot, concentrated plasma of elementary ...

Researchers at Brookhaven National Laboratory's RHIC particle accelerator have determined that an exotic form of matter produced in their collisions is the most rapidly spinning material ever detected ...

Duke University theoreticians said their predictions helped guide the efforts of experimenters using Brookhaven National Laboratory’s Relativistic Heavy Ion Collider (RHIC) atom smasher to create an ...
