CERN scientists find evidence of a particle decay that occurs about once in 10 billion decays

Summary

CERN scientists have found evidence of a particle decay so rare that it happens only once in roughly 10 billion decays, ending a search that spanned more than 40 years. The breakthrough could help physicists uncover hidden particles and forces that lie beyond the reach of today's most powerful accelerators.
