Every fundamental interaction in Physics comes from "some bosonic field" or "force carrier", according to QFT. We have 4 fundamental interactions(force carriers):
- Gravity (Gravitons)
- Electromagnetism (photons)
- Weak nuclear force.(W, Z)
- Strong nuclear force (gluons).
Every field has a source:
- Gravity's source: mass (or more generally energy-momentum in general relativity).
- Electromagnetism: electric charge (also magnetic charges if we include magnetic monopoles or their generalizations in the picture).
- Weak nuclear force: "weak charge" (we could undertand it as "flavor exchange" at the level of the electroweak theory at energies around 80-90GeV).
- Strong nuclear force: "color charge".
With the discovery of the Higgs field, one question naturally arises:
What is the "source"/characteristic of the Higgs boson field? Is the Higgs field "universal" like gravity or it is more like the electroweak or strong fields?
