5 MARCH, 2021 In the final part of the LHC Physics at Ten series, we look at the searches that go beyond our current understanding of the universe An event recorded during 2016 with the CMS detector that contains 10 jets (orange cones) and a muon (red line). (Image: CERN) Count all the known kinds of particles in the universe. Now double it. This is the promise of a family of theoretical models known as Supersymmetry, or SUSY for short. The notion of theories predicting a doubling of observed particles may not be as bizarre as it seems. In fact, it has historical precedent with the story of antimatter.
