A proton-proton collision producing a pair of energetic photons (gamma rays) as seen by the ATLAS detector. The photons are indicated by the red trajectories. An excess of such gamma pairs is among the evidence for the new Higgs candidate particle (Image: CERN)

Article Summary
The recent discovery at the Large Hadron Collider (LHC) of the European Organization for Nuclear Research (CERN) of a massive particle "consistent with" the predicted properties of the Higgs boson hit the news with the force of a hurricane. But the phrase "consistent with" suggests that the CERN observation may also be "consistent with" other types of particle. Is it or isn't it? We're going to attempt to clarify the situation for you.
