Description

We investigate the dependence of the CP3 model and of the SU(2) Yang-Mills theory on the vacuum angle θ. The CP3 model exhibits a first order deconfining phase transition in θ. The critical value of θ runs from π the strong coupling limit towards zero as β is taken to infinity. Qualitatively the same behavior is found in the SU(2) Yang-Mills theory in four dimensions. We discuss the renormalization group trajectories. Only the line with θ=0 allows the cut-off to go to infinity, while the lines with θ>0 end on the line of first order phase transitions. Thus θ is forced to zero in the continuum limit. (orig.)
