Scientists at CERN have detected an extremely rare particle decay process after more than four decades of research. This observation, made through the Large Hadron Collider’s LHCb experiment, involves a B-d meson decaying into a muon and an antimuon, an event that occurs approximately once in every 10 billion relevant particle decays.
The researchers combined data collected during 2024 and 2025 with measurements from earlier experiments conducted between 2011 and 2018 to identify the signal, reaching a statistical significance of 3.2 sigma. While this represents evidence of the decay process, it falls short of the five-sigma standard generally required for a confirmed discovery in particle physics, so the result is not yet considered a definitive discovery.
Scientists are interested in this rare decay process as it can help test the Standard Model, which describes the fundamental particles and forces governing the universe. Any significant deviation from its predictions could indicate previously unknown particles or interactions.
