Physicists studying atomic spin surprised themselves by discovering that spinning protons bizarrely change direction when they crash into larger particles, like the nuclei of gold atoms. On a pool ...
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 ...
An analysis by physicists of colliding protons is tackling the mystery of where protons get their intrinsic property known as spin. Along with neutrons, protons are housed inside an atom's nucleus.
Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have developed a non-invasive way to measure the "spin tune" of polarized protons at the Relativistic Heavy Ion Collider ...
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 ...
Even the people tasked with understanding the most fundamental pieces of our Universe run into surprises. And a surprise has popped up in the data of a decommissioned experiment at America’s largest ...
Scientists analyzing results of spinning protons striking different sized atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) found an odd directional preference in the production of neutrons ...

A new particle collider is set to be built at the Brookhaven National Laboratory in Long Island, New York. Particle colliders smash charged particles against one another at nearly the speed of light ...
For more than 40 years, a subatomic mystery has puzzled scientists: Why do the fragments of splitting atomic nuclei emerge spinning from the wreckage? Now researchers find these perplexing gyrations ...
A team of scientists has for the first time measured the elusive weak interaction between protons and neutrons in the nucleus of an atom. They had chosen the simplest nucleus consisting of one neutron ...
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 ...
