I came across this abstract, and I am curious as to what the ATLAS Team has actually discovered:
Abstract Motivated by the result of the Higgs boson candidates at LEP with a mass of about 115~GeV/c2, the observation given in ATLAS note ATL-COM-PHYS-2010-935 (November 18, 2010) and the publication “Production of isolated Higgs particle at the Large Hadron Collider Physics” (Letters B 683 2010 354-357), 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/c2 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. This channel H→γγ is of great importance because the presence of new heavy particles can enhance strongly both the Higgs production cross section and the decay branching ratio. This large enhancement over the standard model rate implies that the present result is the first definitive observation of physics beyond the standard model. Exciting new physics, including new particles, may be expected to be found in the very near future.
The abstract seems to be from a restricted web site (CERN Log-in required), however I have been able to track down a PDF that seems to be discussing the same phenomenon, however the abstracts are not the same.
Currently, as I understand it, there is a lot of skepticism about the initial Higgs candidate. If this isn't the Higgs, then what part of the standard model is actually being represented? Or is this an entirely new phenomenon?
