I ws pretty impressed with this article, but especially the line-up of the correlation between the Strength of the Higgs interaction vs the mass of the particle (see diagram).

[sciencenews.org]

Extracts:
The Higgs is responsible for the mass of elementary particles, but the mass of composite particles, including protons and neutrons, instead comes mostly from the energy of the particles jangling around within.

The couplings measured so far involve the standard model’s heavier elementary particles. The top quark, for example, is about as heavy as an entire gold atom.

So far, the Higgs has conformed to the standard model.... But there might be discrepancies that just haven’t been detected yet. The standard model predictions agree with measured couplings within error bars of around 10 percent or more. But no one knows if they agree to within 5 percent, or 1 percent.

All the other known elementary particles have a quantum form of angular momentum, known as spin. But the Higgs has a spin of zero, what’s known as a “scalar.” Other types of particles tend to come in families, so it’s not outlandish to imagine that the Higgs boson could have scalar relatives. “It could be there’s a huge scalar sector somewhere hiding and we just saw the first particle of it,” Heinrich says.
