But if technicolour is correct, it would not be able to resolve all the questions left unanswered by the standard model. For example, physicists believe that at the high energies found in the early universe, the fundamental forces of nature were unified into a single superforce. Supersymmetry, physicists' leading contender for a theory beyond the standard model, paves a way for the forces to unite at high energies, but technicolour does not.
Figuring out which theory – if either – is right means combing through more heaps of data to determine if the new signal is real. Budget constraints mean the Tevatron will shut down this year, but fortunately the CDF team, which made the find, is already "sitting on almost twice the data that went into this analysis", says Roser. "Over the coming months we will redo the analysis with double the data."
