One of the most important results obtained for Yang–Mills theory is asymptotic freedom. This result can be obtained by assuming that the coupling constant g is small (so small nonlinearities), as for high energies, and applying perturbation theory.
Is quantum electrodynamics a Yang-Mills theory?
By the 1950s, when Yang–Mills theory was discovered, it was already known that the quantum version of Maxwell theory – known as Quantum Electrodynamics or QED – gives an extremely accurate account of electromagnetic fields and forces.Jun 9, 2021
Is Yang-Mills theory solved?
Yang–Mills theory exists and satisfies the standard of rigor that characterizes contemporary mathematical physics, in particular constructive quantum field theory, and. The mass of the least massive particle of the force field predicted by the theory is strictly positive.
Why is the Yang-Mills mass gap important?
The successful use of Yang-Mills theoryYang-Mills theoryIn mathematical physics, Yang–Mills theory is a gauge theory based on a special unitary group SU(N), or more generally any compact, reductive Lie algebra. ... Thus it forms the basis of our understanding of the Standard Model of particle physics.https://en.wikipedia.org › wiki › Yang–Mills_theoryYang–Mills theory - Wikipedia to describe the strong interactions of elementary particles depends on a subtle quantum mechanical property called the "mass gap": the quantum particles have positive masses, even though the classical waves travel at the speed of light.
Is Yang-Mills theory correct?
The current state of Yang-Mills theory has been compared to the early days of the calculus, when undeniably accurate and useful results were being obtained but before the formal development of analysis added rigorous definitions that eliminated logical fallacies.
