| Popis: | Recent experiments in heavy ion collisions have shown the possibility of creating parity-odd domains resulting from the $\theta$ term in strong interaction Lagrangian. The $\theta$ term originates from the nontrivial solution of QCD vacuum known as the $\theta$ vacuum, and the value of $\theta$ is taken to be a function of spacetime coordinates in the parity-odd domains. This means that we have to consider different theories at each point so that we need to devise a new approach to define the QCD vacuum. In this Letter, we suggest a method to generalize the $\theta$ vacuum by exploiting the dimension 2 condensates and to calculate the parity-odd domain structure as the union of gauge slices defined by the constant value of dimension 2 condensate.
