It has been 15 years since the Large Hadron Collider (LHC) started smashing particles together. Since then, I have been one among thousands of researchers scouring its collisions for evidence of new physics that could explain mysteries like dark matter or the existence of matter in the universe. In 2012, the LHC uncovered the Higgs boson, securing the foundations of the standard model – our current best theory of fundamental particles and their workings. However, despite high hopes, it has yet to reveal new physics.
