Physicists have found signs of a particle decay so rare it should occur only about once in every 10 billion "beauty" particles.

LHCb, CERN's upgraded experiment at the Large Hadron Collider, produced the result after a hunt lasting over four decades.

Physicists step closer to the 'Zeptoverse' after 42-year particle search

CERN physicists have spotted evidence of a very rare B0 meson decay that produces a muon and its antiparticle.

The process was first predicted in 1984, and the result helps test Standard Model forecasts.

After 40 years of searching, physicists find evidence for an ultrarare particle decay
