The status of supersymmetry

Once the most popular framework for physics beyond the Standard Model, supersymmetry is facing a reckoning--but many researchers are not giving up on it yet. The Standard Model of particle physics is both fantastically successful and glaringly incomplete. Its predictions have pieced together many of the known features of the universe and guided physicists to new discoveries, such as the Higgs boson. But it cannot account for the existence of dark matter--the mysterious substance that makes up 85...
