• Resumen

  • An energy excess spotted in 20-year-old data suggests so. The bump hints at the existence of a previously undetected particle, which could change people's understanding of physics. The ALEPH particle detectorat CERN near Geneva, Switzerland, switched on in July 1989. For the next l5 years, it analyzed the decays of millions of Z particles created in the Large Electron-Positron collider-located in the same tunnel that now houses the Large Hadron Collider.
