"If the blips in the debris of the Tevatron particle smasher really are signs of the Higgs boson then it's not what we expected. It might mean that it's time to replace the standard model with a more complex picture of the universe"
On 9 December last year, as John Conway looked at the results of his experiment, a chill ran down his neck. For 20 years he has been searching for one of the most elusive things in the universe, the Higgs boson - aka the God particle - which gives everything in the cosmos its mass. And here, buried in the debris generated by the world's largest particle smasher, were a few tantalising hints of its existence.
Conway first revealed the news of his experiment earlier this year in a blog. Experimental particle physicists are sceptics by nature, loath to claim the discovery of any new particle, let alone a particle of the Higgs's stature, and in his blog Conway dismissed hints of its existence as an aberration, just as many other supposed signs of the elusive particle have proved to be after closer examination. The tiny blips in Conway's data have so far simply refused to go away.
What's more, using data made public last week in a second blog, another team of researchers has independently seen hints of a new particle with similar mass. Both results may yet be dismissed, but the coincidence is striking, and is one that is getting physicists excited. If they have found evidence of a Higgs particle, then it points towards the existence of a universe in which each and every particle we know of has a heavier "super-partner", an arrangement of the cosmos known as supersymmetry.
The Higgs boson is infamous as the only particle predicted by the standard model of physics that remains undetected. In theory, every other particle in the universe gets its mass by interacting with an all-pervading field created by Higgs bosons. If the Higgs is discovered, the standard model could justifiably claim to be the theory that unifies everything except gravity.
