This discovery is so abstract, being a statistical analysis of trillions upon trillions of events, that there is literally nothing to show for it. Not one of these events involved the detection of a Higgs Boson, per se. Here is the photograph that constitutes the discovery of the positron in 1932, 4 years after it was hypothesized by Dirac. There it is. That's a discovery.
That's not a positron, per se.
Not familiar with the statistical analysis, but I’m guessing they would probably counter that indirect evidence is still evidence. That’s not as satisfying to me as direct evidence, but they have a point.
