Vacuum degeneration in the quasiclassical approximation in non-Abelian quantum theory

Abstract

In this paper we construct quasiclassical wave packets for a non-Abelian particle in an external chromomagnetic field and field-averaged coordinates and color vector. In this case the average color vector is found not to satisfy the quasiclassical Wong equations and vacuum degeneration is noted in such a field. The choice of the vacuum leads to spontaneous breakdown of the initial symmetry of the Hamiltonian.
