摘要：

We analyze two recent models based on the gauge group SU(3)(c)xSU(3)(L)xU(1)(N) where each generation is not anomaly-free, but the anomaly cancels when three generations are taken into account. We show that the most general Yukawa couplings of these models admit a Peccei-Quinn symmetry. This symmetry can be extended to the entire Lagrangian by using extra fields in a very elegant way so that the resulting axion can be made invisible.
