Is the Higgs boson really the Higgs boson?

In 2012, CERN discovered a new boson, likely the Higgs boson, with a mass of 125 GeV. This particle aligns with the Standard Model but suggests potential theories beyond it, such as supersymmetry and Technicolor. The Higgs boson may not be unique, and further data is needed to explore additional Higgs bosons or composite structures.

What does the Standard Model predict about the Higgs boson?

What are some theories that go beyond the Standard Model of particle physics?
