Has the LHC discovered supersymmetry?
Has the LHC discovered supersymmetry? It appears increasingly unlikely that supersymmetry could include all three features—an explanation for the Higgs mass, a dark matter particle and force unification—found in the pre-LHC models. The lack of evidence for supersymmetry at the LHC does not signify a death knell for the idea. Is supersymmetry a real thing? Dozens of supersymmetric theories exist. Supersymmetry is a spacetime symmetry between two basic classes of particles: bosons, which have an integer-valued spin and follow Bose–Einstein statistics, and fermions, which have a half-integer-valued spin and follow Fermi-Dirac statistics. What is the difference between a particle and...
