It's a boson! But we need to know if it's the Higgs

If we don't know the new particle is a Higgs, what do we know about it?
We know it is some kind of boson, says Vivek Sharma of CMS, one of the two Large Hadron Collider experiments that presented results on Wednesday. There are only two types of elementary particle in the standard model: fermions, which include electrons, quarks and neutrinos, and bosons, which include photons and the W and Z bosons. The Higgs is a boson – and we know the new particle is too because one of the things it decays into is a pair of high-energy photons, or gamma rays. According to the rules of mathematical symmetry, only a boson could decay into exactly two other photons.
Anything else?
Another thing we can say about the new particle is that nothing yet suggests it isn't a Higgs. The standard model, our leading explanation for the known particles and the forces that act on them, predicts the rate at which a Higgs of a given mass should decay into various particles. The rates of decay reported for the new particle yesterday are not exactly what would be predicted for its mass of about 125 gigaelectronvolts (GeV) – leaving the door open to more exotic stuff. "If there is such a thing as a 125 GeV Higgs, we know what its rate of decay should be," says Sharma. But the decay rates are close enough for the differences to be statistical anomalies that will disappear once more data is taken. "There are no serious inconsistencies," says Joe Incandela, head of CMS, who reported the results on Wednesday.
