| The existence of a Higgs boson would be the simplest solution to the problem of electroweak symmetry breaking. |
| The idea behind grand unification is that at sufficiently high energies, the strong and electroweak forces lose their identities and merge into a more fundamental interaction. |
| Electric interactions and weak interactions were joined into a common electroweak interaction in the 1960's by commonly Salam, Glashow, Weinberg, etc. |
| The right application turned out to the unification of the electromagnetic and weak interactions into a single electroweak force. |
| Quantum electrodynamics, and its expansion to the electroweak Standard Model of particle physics, is also a quantum field theory. |
| The electroweak and strong interactions coexist in a combined theory of the fundamental interactions called the standard model. |
