| dc.description | One may argue that QCD solves the strong CP problem by itself, without having to introduce new symmetries and particles. To test this idea, a lattice simulation is performed. The problem is investigated in the CP$^3$ model first. It is found that the model has a first order phase transition in $θ$ from a confining phase at small $θ$ to a deconfining phase at large $θ$, 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. Preliminary studies of the SU(2) Yang-Mills theory in four dimensions show a phase transition in $θ$ as well, so that it is quite likely that the strong CP problem in QCD is solved along the same line. | |
