If the collider does not detect the Higgs within two years, researchers say they will know that it does not exist - at least in the form required by the Standard Model, the framework which was devised to explain the behaviour of fundamental particles.
"The Higgs is one model of many," according to Professor LeCompte.
"It's a model that we like. It's simple, its elegant, but it's entirely possible that there is something else beyond the Higgs that does its job instead, and what we may discover is instead of the Higgs itself we may discover something much more interesting."
