New theory work at the US 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 blocks: quarks. The result, published in Physical Review Letters, agrees with recent experiments and supercomputer calculations.
