We apply to the CP^9 model two recently proposed numerical techniques for the simulation of systems with a theta-term. The algorithms, successfully tested in the strong coupling limit, are applied to the weak coupling region. The results agree and errors have been evaluated and are at the % level. The results scale well with the renormalization group equation and show that, for CP^9 in the presence of a theta-term, CP symmetry is spontaneously broken at $\theta=\pi$ in the continuum limit.

Abstract: | We apply to the CP^9 model two recently proposed numerical techniques for the simulation of systems with a theta-term. The algorithms, successfully tested in the strong coupling limit, are applied to the weak coupling region. The results agree and errors have been evaluated and are at the % level. The results scale well with the renormalization group equation and show that, for CP^9 in the presence of a theta-term, CP symmetry is spontaneously broken at $\theta=\pi$ in the continuum limit. |
