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 ...

A boiling sea of quarks and gluons, including virtual ones—this is how we can imagine the main phase of high-energy proton collisions. It would seem that particles here have significantly more ...

An atom is about 10^-10 m in size. The next smallest thing in nature is the nucleus, which is about 100,000 times smaller, i.e., 10^-15 m in size — a femtometer, or “fermi.” A nucleus is composed of ...

For a few millionths of a second after the Big Bang, the universe consisted of a hot soup of elementary particles called quarks and gluons. A few microseconds later, those particles began cooling to ...

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 ...

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 ...

Recreating the conditions present just after the Big Bang has given experimentalists a glimpse into how the universe formed. Now, scientists have begun to see striking similarities between the ...

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 ...

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, ...

The fastest rotating fluid ever seen has been created by an international team of physicists working on the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory in the US. The ...

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 ...

For a quarter of a century, physicists have faced a paradox regarding the net spin of protons and neutrons – the spin of their constituent quarks accounts for only a small fraction of their overall ...
