UPTON, NY -- If you want to unravel the secrets of proton spin, put a "twist" in your colliding proton beams. This technique, tried and perfected at the Relativistic Heavy Ion Collider (RHIC)--a ...

UPTON, NY - Scientists hoping to unravel the mystery of proton spin at the Relativistic Heavy Ion Collider (RHIC, http://www.bnl.gov/rhic/), a 2.4-mile-circumference ...

Calculating a proton's spin used to be an easy college assignment. In fact, Carl Gagliardi remembers answering that question when he was a physics graduate student in the 1970s. But the real answer ...

Nuclear physicists have long been working to reveal how the proton gets its spin. Now, a new method that combines experimental data with state-of-the-art calculations has revealed a more detailed ...

When the universe first burst into being, all of space was a cosmic cauldron filled with a roiling, fiery liquid of fundamental particles heated to trillions of degrees. But this seething primordial ...

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 collaboration of nuclear theorists has used supercomputers to predict the spatial distributions of charges, momentum, and other properties of 'up' and 'down' quarks within protons. The calculations ...
