Two Higgs Bosons? CERN Scientists Revisit Large Hadron Collider Particle Data (Huffington post)

**By Michael Moyer**

A month ago scientists at the Large Hadron Collider released the latest Higgs
boson results. And although the data held few obvious surprises, most
intriguing were the results that scientists didn’t share.

The original Higgs data from back in July had shown that the Higgs seemed to
be decaying into two photons more often than it should—an enticing though
faint hint of something new, some sort of physics beyond our understanding. In
November, scientists at the Atlas and LHC experiments updated everything
_except_ the two-photon data. This week we learned why.

Yesterday researchers at the Atlas experiment finally updated the two-photon
results. What they seem to have found is bizarre—so bizarre, in fact, that
physicists assume something must be wrong with it. Instead of one clean peak
in the data, they have found two. There seems to be a Higgs boson with a mass
of 123.5 GeV (gigaelectron volts, the measuring unit that particle physicists
most often use for mass), and another Higgs boson at 126.6 GeV—a statistically
significant difference of nearly 3 GeV. Apparently, the Atlas scientists have
spent the past month trying to figure out if they could be making a ...
