How do physicists know when they’ve found a Higgs boson?

I know the Higgs field and the capabilities of the Higgs Boson, but I could never understand how physicists concluded the finding of a Higgs Boson

Does this insights article help: LHC Part 4: Searching for New Particles and Decays?

There is also a Wikipedia article Search for the Higgs boson, with a completely different approach.

You get data and compare them to your current theory's predictions... if you analyze everything correctly and the data deviate significantly from your predictions; you've found something new...
