QCD with a θ-VACUUM Term:. a Complex System with a Simple Complex Action
Abstract
We reanalyze in the first part of this paper the old question of P and CT realization in QCD. The second part is devoted to establish general results on the phase structure of this model in the presence of a θ-vacuum term.
