CERN confirms: Hints of hypothetical particle have disappeared

Toward the end of last year, the people behind the Large Hadron Collider announced that they might have found signs of a new particle. Their evidence came from an analysis of the first high-energy data obtained after the LHC’s two general-purpose detectors underwent an extensive upgrade. While the possible new particle didn’t produce a signal that reached statistical significance, it did show up in both detectors, raising the hope that the LHC was finally on to some new physics.
