Example sentencesExamples
- Today the other three forces are described by the gauge theories of quantum chromodynamics and quantum electrodynamics, which together make up the Standard Model of particle physics.
- Then similar wisdom was applied to the strong nuclear force to yield quantum chromodynamics, or QCD, and this theory was also renormalizable.
- The theory of the strong interaction between quarks - quantum chromodynamics - is approximately invariant under what is called charge symmetry.
- Everyone agrees that the fundamental theory of the strong interaction is a quantum field theory known as quantum chromodynamics, or QCD for short.
- The theory of strong interactions, known as quantum chromodynamics, is well-developed and consistent with experiments, although it is not easy to test it very precisely.
