The 50-year quest to find the particle that almost broke physics

When physicists first discovered a form of a radioactivity called beta decay it seemed to violate the laws of physics. It took 50 years to work out what was going on

Bottom view of the LEGEND-200 liquid argon cryostat and the enclosing water tank. The inner walls of the water tank and the outer wall of the cryostat are covered with a wavelength-shifting mirror film. The purpose is to shift and reflect the light produced by muons via the Cherenkov effect in the water. The photons are detected by photosensors. The purpose of this detector component is to detect and identify cosmic ray muons, some of which still reach the experiment despite being located deep underground the Gran Sasso mountain. (fyi: The muon flux is reduced by a factor 106 (one million) by the rock). If not identified, the muon induced events could mimic the searched signal events.
