Effective 't HooftPolyakov Monopoles from Pure SU(3) Gauge Theory
Abstract
The wellknown topological monopoles originally investigated by 't Hooft and Polyakov are known to arise in classical YangMillsHiggs theory. With a pure gauge theory, it is known that the classical YangMills field equation do not have such finite energy configurations. Here we argue that such configurations may arise in a semiquantized YangMills theory, where the original gauge group, SU(3), is reduced to a smaller gauge group, SU(2), and with some combination of the coset fields of the SU(3) to SU(2) reduction acting as effective scalar fields. The procedure is called semiquantized since some of the original gauge fields are treated as quantum degrees of freedom, while others are postulated to be effectively described as classical degrees of freedom. Some speculation is offer on a possible connection between these monopole configurations and the confinement problem, and the nucleon spin puzzle.
