The most coveted prize in particle physics - the Higgs boson - may have been glimpsed, say researchers reporting at the Large Hadron Collider (LHC) in Geneva.
The particle is purported to be the means by which everything in the Universe obtains its mass. Scientists say that two experiments at the LHC see hints of the Higgs at the same mass, fuelling huge excitement. But the LHC does not yet have enough data to claim a discovery.
Finding the Higgs would be one of the biggest scientific advances of the last 60 years. It is crucial for allowing us to make sense of the Universe, but has never been observed by experiments. more...
