times larger than the mass of the Higgs boson. The excess photons turned up
while searching through data looking for gravitons. By themselves the data are
not very significant and would not have garnered much interest, but this
becomes more interesting since both experiments saw these statistical bumps in
the same place. The next round of data taking in March will be able to
determine whether this particle really exists.

In addition to what they might have found, also of interest is what they
haven't found:

Meanwhile, searches for particles predicted by supersymmetry, physicists'
favourite extension of the standard model, continue to come up empty-handed.
To theoretical physicist Michael Peskin of the SLAC National Accelerator
Laboratory in Menlo Park, California, the most relevant part of the talks
concerned the failure to find a supersymmetric particle called the gluino in
the range of possible masses up to 1,600 GeV (much farther than the 1,300-GeV
limit of Run 1). This pushes supersymmetry closer to the point where many
physicists might give up on it, Peskin says.

I have no mass predictions, but the theory I'm working on sometimes implies 2 Higgs types so 1 more to find, a 'plankon' spin 1 particle and a spin 2 heavy graviton still to be found.

The heavy graviton idea does not cause acceleration directly, it causes a rate of change of acceleration. Acceleration of dark matter is conserved, (no heavy gravitons, as no mass) and changes in gravitational acceleration propagate slower than the speed of light (as heavy), therefore dark energy, as beyond a certain speed, the field gradient gravitons can not catch up.

===========================
so what happened to the God particle Higgs
now we have many Gods
do we have here a new '[modern

The article you are quoting is referring to an old version of an article in
the online version of “Nature” which has been corrected:

| 15 December 2015 | Corrected: 16 December 2015
| […]
| The results largely match a rumour that has been circulating on social
| media and blogs for several days: that both the CMS and ATLAS detectors at
| the LHC have seen an unexpected excess of pairs of photons, together
^^^^^^^^
| carrying around 750 gigaelectronvolts (GeV) of energy, in the debris of
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
| their proton–proton collisions. This could be a tell-tale sign of a new
| particle — also a boson, but not necessarily similar to the Higgs —
| decaying into two photons of equivalent energy. If so, the particle would
| be about four times more massive than the next heaviest particle
| discovered so far, the top quark, and six times more massive than the
| Higgs.

| Corrected:
| An earlier version of this article stated, incorrectly, that the two
| photons have masses of about 750 GeV each and that the new particle would
| have a mass of 1,500 GeV.
