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

One of the great theoretical challenges facing physicists is understanding how the tiniest elementary particles give rise to most of the mass in the visible universe. A physicist from MIT will talk ...

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 ...

Pentaquarks do not fit into the traditional quark model of hadrons, but understanding these exotic new particles is offering fresh insights into the subtleties of the strong interaction Five quarks In ...

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, ...

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 ...

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 ...

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 ...

An unusual alliance between physicists who study ultrahot plasmas and ultracold atoms is yielding intriguing results – and may even lead to an experimental test for string theory, as Barbara Jacak ...

The whole is equal to the sum of its constituent parts. That's how everything works, from galaxies to planets to cities to molecules to atoms. If you take all the components of any system and look at ...

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 ...
