Trivial Solution to the Domain Wall Problem

Abstract

The domain wall problem only arises if one makes the unrealistic pure gauge assumption. The problem is avoided altogether by relaxing this assumption. Recently much attention has been devoted to solving the domain wall problem (Sikivie 1982). Our contention is that the problem does not really exist. The domain wall problem arises because it is commonly believed that the anomaly (via instantons) explicitly" breaks V(l) axial invariance down to the centre ZL (where L is the number of light quark flavours). The subsequent spontaneous breaking] of this centre by the QeD condensate
