The Easter Bunny dropped in his comment section the abstract of a
sensational ATLAS internal note, which says
...we studied the γγ invariant mass distribution over the range of
80 to 150 GeV/c2. With 37.5 pb−1 data from 2010 and 26.0 pb−1 from 2011,
we observe a γγ resonance around 115 GeV with a significance of 4σ.
The event rate for this resonance is about thirty times larger than the
expectation from Higgs to γγ in the standard model...
So, the note claims no less than a firm evidence for a 115 GeV Higgs boson
decaying into 2 photons. This decay occurs in the standard model with the
amplitude dominated by a W-boson loop. However, this decay is very rare -
only about 0.2 percent of Higgses decay this
