Supersymmetry and the crisis in physics.

Supersymmetry postulates that every known particle has a hidden superpartner. Physicists love supersymmetry because it solves a number of problems that crop up when they try to extend our understanding of quantum mechanics. It would also potentially solve the mystery of the universe’s missing dark matter. Physicists hoped to fi nd evidence of supersymmetry in experiments at the Large Hadron Collider (LHC). To date, they have not. If no evidence arises in the next run of the LHC, supersymmetry will be in trouble. The failure to fi nd superpartners is brewing a crisis in physics, forcing researchers to question assumptions from which they have been working for decades.
