Proton puzzle puts physicists in a whirl
The more deeply particle physicists probe the proton's structure, the more complicated it seems to get. The lastest experimental result to spur theorists into a flurry of speculation concerns the proton's spin, which is the source of its magnetism. This experiment suggests that very little -- perhaps none -- of the proton's spin comes from the spins of the quarks that are thought to make up a proton. The result raises serious questions about how the proton is put together.
"This is not an experiment telling us about esoteric things that happened in the first microsecond of the Big Bang or in some remote part of ...
