Description

One may argue that QCD solves the strong CP problem by itself. To test this idea, a lattice simulation suggests itself. In view of the difficulty of such a calculation we have, as a first step, investigated the problem in the CP3 model. The CP3 model is in many respects similar to QCD. In this talk I present some first results of our calculation. Among other things it is shown that the model has a first order deconfining phase transition in θ and that the critical value of θ decreases towards zero as β is taken to infinity. This suggests that θ is tuned to zero in the continuum limit. ((orig.))
