Spontaneous CP breaking and the axion potential: an effective Lagrangian approach

<!--HTML--><p>After a quick review of the U(1) and strong-CP problems in QCD I will turn to some recent work on spontaneous CP violation in QCD at vacuum angle $\theta = \pi$ and to its possible relevance for determining the axion potential at temperatures up to the deconfinement tempera...
