Hints of discovery fade away with new data from Large Hadron Collider
CHICAGO — Particle physicists’ hopes have been dashed. A possible new particle hasn’t been sighted in new data from the Large Hadron Collider, scientists reported August 5 at the International Conference on High Energy Physics.
Physicists from LHC experiments CMS and ATLAS first unveiled hints of the new particle in December 2015 (SN: 1/9/16, p. 7). In the months that followed, enthusiastic physicists published hundreds of papers proposing theoretical explanations (SN: 5/28/16, p. 11).
Evidence of the particle, in the form of a bump on a plot — an excess of events at a particular energy — popped up after the LHC, at the European particle physics laboratory CERN near Geneva, began smashing together
