A strange ‘neutrino force’ helped heal a crack in particle physics
Neutrinos and other particles can produce a subtle force, relevant for precise measurements
Neutrinos are so elusive that large detectors are needed to spot them. ProtoDUNE (pictured) is a prototype for a future, much larger neutrino detector, DUNE. Now, physicists have found that an even more subtle effect, a neutrino force, could be affecting the results of experiments with cesium atoms.
