Аннотация
From the consideration of the topological structures of Yang-Mills theories, we obtain the results thatSU(2) Yang-Mills theory in the Minkowski space has the vacua of topologyZ?Z2. Therefore, we argue that the physical vacuum ofSU(2) Yang-Mills theory needs to be described by two vacuum angles ? and . Consequently, even if ?=0, a non-vanishing angle can still induce spontaneous CP violations in such gauge theories.
