We present the basic non-perturbative structure of classical dynamical solutions and one particle quantum states in SU(3) Yang-Mills theory. The Weyl group of su(3) algebra plays a crucial role in constructing these solutions and has profound effects on the structure of the classical and quantum Yang-Mills theory. Our study reveals that the Weyl group allows for singlet irreducible representations on the space of classical dynamical solutions, which provides a strict concept of one particle quantum states for gluons and quarks. We propose a non-perturbative approach based on Weyl symmetric solutions to fully nonlinear equations of motion, resulting in a full space of dynamical solutions classified by a finite set of integer numbers.
We present the basic non-perturbative structure of the space of classical dynamical solutions and corresponding one particle quantum states in SU (3) Yang-Mills theory. It has been demonstrated that the Weyl group of su(3) algebra plays an important role in constructing non-perturbative solutions and leads to profound changes in the structure of the classical and quantum Yang-Mills theory. We show that the Weyl group as a non-trivial color subgroup of SU (3) admits singlet irreducible representations on a space of classical dynamical solutions which lead to strict concepts of one particle quantum states for gluons and quarks. The Yang-Mills theory is a non-linear theory and, in general, it is not possible to construct a Hilbert space of classical solutions and quantum states as a linear vector space, so, usually, a perturbative approach is applied. We propose a non-perturbative approach based on Weyl symmetric solutions to full non-linear equations of motion and construct a full space of dynamical solutions representing an infinite but countable solution space classified by a finite set of integer numbers. It has been proved that the Weyl singlet structure of classical solutions provides the existence of a stable non-degenerate vacuum which serves as a main precondition of the color confinement phenomenon. Some physical implications in quantum chromodynamics are considered.(c) 2023 Published by Elsevier B.V.
