CERN Experiment Detects Ultra-Rare Particle Decay Consistent with Standard Model

Physicists at CERN's LHCb experiment have found evidence of an ultra-rare particle decay, occurring approximately once in 10 billion beauty particle decays. This discovery, announced during a CERN seminar, aligns with the Standard Model of particle physics, a search spanning over 40 years. The finding could assist in the ongoing quest for new particles and forces beyond current accelerators, utilizing data analyzed from 2011-2018 and 2024-2025.
