Abstract

In a previous paper we pointed out that dual QCD in its original form violated unitarity. In this paper we identify the cause for this violation and construct a new dual QCD Lagrangian which is unitary. We have not yet been able to determine whether this new Lagrangian leads to confinement. Finally we point out how our original dual QCD Lagrangian which successfully describes many of the aspects of the physics of confinement can be regarded as a phenomenological Lagrangian which does not violate unitarity at the classical or tree level.
