Can a new collider reveal the last secrets of the Higgs boson?
The most famous subatomic particle has revealed nothing we didnt expect  so far. Now physicists want to build a Higgs factory to better interrogate it for signs of new physics  Tom Straw  FOR half a century, finding the Higgs boson was top of particle physicists to-do lists. Its eventual discovery in 2012 was celebrated as the final piece of the puzzle to complete the standard model, our picture of reality at its most fundamental level. The Higgs became famous, a rare household name among elementary particles. But now, almost a decade on, we still barely know the Higgs boson  and our understanding of the pantheon of particles and forces that makes the universe what it is remains manifestly imperfect. We were hoping that, alongside the Higgs, new particles and forces
