A search for evidence of particles predicted by supersymmetry—a favored extension of the standard model—suggests that if the theory is correct, it may be more complicated to discover these particles than previously thought.
A paper appearing in Physical Review Letters announces the latest—and most extensive—search for evidence that a candidate theory, called supersymmetry, which explains dark matter and unifies three of the fundamental forces, is correct [1]. As reported by the CMS collaboration at CERN’s Large Hadron Collider (LHC), no particles predicted by supersymmetry have been found, suggesting that the theory is likely more complicated than many had hoped.
