Parsing the puzzle of nucleon spin

Newport News VA (SPX) Nov 30, 2023

Alexandre Deur has spent his career studying the mystifying spin structure of the nucleon - which is also one of the primary missions of the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility, where Deur has been a staff scientist for nearly 20 years. A particle's spin is one of its basic characteristics, like its mass or electric charge, and physicists have long tr
