Like a quantum version of a whirling top, protons have angular momentum, known as spin. But the source of the subatomic particles’ spin has confounded physicists. Now scientists have confirmed that ...
New theory work at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has shown that more than half of the spin of the proton is the result of the movement of its building ...
Researchers find a new contribution to the proton Sivers function that describes the internal rotation of the proton perpendicular to its velocity An important question for scientists studying the ...

Scientists achieve the impossible by creating matter from empty space
Something has been lurking in empty space, and for the first time, physicists may have caught it leaving fingerprints.
Given the choice of three different 'spin' orientations, certain particles emerging from collisions at the Relativistic Heavy Ion Collider (RHIC), an atom smasher, appear to have a preference. Recent ...
