Read moreSifting out the sources of spin
Along with the neutron, the proton is the basic building block of the atomic nucleus. But, the source of the proton’s spin—a fundamental property, along with charge—has been a long standing puzzle to ...
Physics and Astronomy | Read moreShortest flashes from ultra-hot matter
This is shown in calculations of the light emission of so-called quark-gluon plasmas, which are created in such collisions for extremely short periods of time. Under certain conditions, double flashes...
Physics and Astronomy | Read moreAtomic physics study sets new limits on hypothetical new particles
In a forthcoming Physical Review Letters article, a group of physicists at the University of Nevada, Reno are reporting a refined analysis of experiments on violation of mirror symmetry in atoms that ...

The Large Hadron Collider is an enormous particle accelerator whose 17-mile tunnel straddles the borders of France and Switzerland. A group of physicists at the University of Nevada, Reno has analyzed...
Physics and Astronomy | Read moreBreaking symmetry in the strong force
An international research team has reconciled two theories that explain the properties of the pion. The work is important because this subatomic particle plays a key role in the strong interaction—the...

Also known as the Quark Matter conference, the meeting is the premier conference in the field of high-energy nuclear physics, with typically 600 or more attendees. This 21st-in-the-series meeting will...
Event News | Read moreFermilab collider experiments discover rare single top quark
The discovery of the single top confirms important parameters of particle physics, including the total number of quarks, and has significance for the ongoing search for the Higgs particle at Fermilab’...
Physics and Astronomy | Read moreUltracold gas mimics ultrahot plasma
Several years after Duke University researchers announced spectacular behavior of a low density ultracold gas cloud, researchers at Brookhaven National Laboratory have observed strikingly similar prop...
Physics and Astronomy | Read moreScience: what is the origin of the visible mass of the universe?
An international team of scientists has for the first time computed the masses of one of the most important constituents of matter - protons and neutrons. The tool which contributed the most to this c...
Information Technology | Read moreGluons don’t explain the spin surprise
Scientists have acquired more clues in the mystery of how the spin, or intrinsic angular momentum of a nucleon (proton or neutron), results from its constituent parts, quarks and gluons. Marco Stratma...
Physics and Astronomy | Read moreFuzziness on the Road to Physics' Grand Unification Theory
At issue are grand unified theories that first appeared in the 1970s. They have suggested that, at short distances or high-energy scales, electromagnetic forces, strong forces, which bind quarks in pr...
Physics and Astronomy | Read moreA four-dimensional picture of our three-dimensional world
An international team of scientists from RIKEN at Brookhaven National Laboratory (BNL) and elsewhere in the USA, Japan and the UK are testing the Standard Model—the foundation of high-energy physics t...
