It looks like they are trying to subtract all the other decay sources of b quarks, from the observed b quarks, and attribute them to the decay of the Higgs boson. Which would be quite the feat. There could be many other particles hidden from view by such processes. I don't really know how possible this is. My question was isn't there a better way than saying 5 sigma. In the case for this article, apparently there are very few Higgs produced, so it would not amount to even a hundred thousand, which in that case I would think the criteria should not even be 5 sigma, but less than that. Thoughts?
