A new way of studying matter that is created when photons collide has been developed by CERN’s Compact Muon Solenoid (CMS) collaboration. Their experiment, done on the Large Hadron Collider (LHC), sheds new light on a mystery surrounding the nature of high-energy collisions between heavy ions. While the team’s results are consistent with the expectations of the Standard Model of particle physics, they hope that further observations could lead to observations that could challenge our conventional understanding of physics.
