An update on the Higgs-like resonance discovered last summer was given by the ATLAS experiment on Dec. 13, indicating that the decay to two photons is about 2 standard deviations off of the standard model value, which may indicate that there are additional new particles within reach of the Large Hadron Collider.

The largest discrepancy is in the Higgs-like boson decaying to two photons (H → γ γ).
