| + | <blockquote>Supersymmetry (SUSY) is decidedly not a new symmetry. It was devised and applied to hadronic physics nearly a half century ago. If nature were supersymmetric, every known fermion would have a spinless superpartner, every known boson a spin-1/2 superpartner. Particles and their partners would have the same mass. At best, SUSY is a badly broken symmetry because no superpartner has yet been seen. Even as a broken symmetry, SUSY is theoretically attractive and phenomenologically useful. Evidence for supersymmetric particles has been sought at accelerator laboratories throughout the world and by several generations of high-energy experimentalists. No trace of SUSY has been detected, not even at today’s most powerful particle collider, the LHC at CERN. It appears that the energy scale associated with any still viable SUSY scheme is likely too high for the theory to fulfil its several assigned tasks: stabilize the Higgs boson mass, provide a dark matter candidate, and enable the coupling-constant convergence predicted by grand unification. Perhaps the time has come for experimenters to peer beyond their supersymmetric chimera. | ||
