The Higgs is thought to be in the range greater than but close to 114 GeV, although there are some ways to get around this. Supersymmetric partners are theoretically in the 100-1000s GeV range. The proton however (~1 GeV as mentioned above) is made of up and down quarks which are < 0.01 GeV.

Particle physics *appears* to be in a foundational crisis, but I freely admit that it is outside my area of expertise.

That’s a bit more than six times the mass of the proton.
