...this is massive news for particle physicists and the Standard Model.

I notice that the researchers are quoting a 9σ level of confidence in their findings and data - much higher than the minimum 5σ level demanded in Particle Physics collision experiments (the recent Higgs Boson discovery was at a confidence level of 5σ)

5σ = 99.99994%

9 sigma levels has a lot of 9's
