> This observation, which has a significance of 5.9 standard deviations, corresponding to a background fluctuation probability of 1.7x10^-9, is compatible with the production and decay of the Standard Model Higgs boson.
Technically it could be another particle with a 126GeV mass, though that's hopefully something more experiments will show one way or the other.
If you have more questions about physics, ask /r/physics on Reddit. They people there are very nice and include several serious physicists.

On a more serious note, it appears that the Nobel Prize can be awarded to organizations, which would make CERN the most likely recipient. This said, as far as I can say only the Nobel Peace Prize has been awarded in such a way in the past.
Standard procedure is to list all the researchers involved in the project. Not everyone will be directly involved in the specific analysis to find the Higgs.
