Zeptoverse Clue: CERN Finds Rare Particle Decay
Scientists at CERN, working on the LHCb experiment, say they have found evidence of a rare particle decay. The search had gone on for 42 years. Reports describe it as a step toward the so-called zeptoverse, a term for physics at extremely small scales.

Context: CERN is the European lab near Geneva that runs the Large Hadron Collider, a giant ring that smashes particles together. LHCb is one of its detectors, and rare decays like this help physicists test their theories of how matter works.
