Physicists at the Fermi National Accelerator Laboratory have found more evidence that a subatomic particle is behaving unexpectedly. And the reason could be evidence of a new, fifth force of nature.

Electric and magnetic fields both exert forces on charged particles. The motion of charged particles in these fields can be determined and used in particle ... from atomic line spectra supports ...
