"Finding the Higgs would mark the closing of one chapter in this story. The elusive boson rounds off what has become known as the Standard Model of physics—an explanation that relies on 17 fundamental particles and three physical forces (though it stubbornly refuses to accommodate a fourth force, gravity, which is separately explained by Albert Einstein’s general theory of relativity). Much more intriguingly, the Higgs also opens another chapter of physics.

The physicists’ plan is to use the Standard Model as the foundation of a larger and more beautiful edifice called Supersymmetry. This predicts a further set of particles, the heavier partners of those already found. How much heavier, though, depends on how heavy the Higgs itself is. The results just announced suggest it is light enough for some of the predicted supersymmetric particles to be made in the LHC too."
