Researchers make progress toward solving the proton spin puzzle

Scientists in a research group led by Constantia Alexandrou, professor of physics at the University of Cyprus and the Cyprus Institute, made a crucial step towards solving a three-decades-old puzzle: They have successfully deciphered the total angular momentum (spin) of the nucleon, determining how it's shared among its constituents. CSCS supercomputer Piz Daint provided the necessary computational resources.
