Flavor mixing and rare B and K decays in the minimal 331 model

We analyze the implications of the minimal 331 model with respect to flavor physics. These new contributions stem from the tree level exchange of a flavor changing additional Z' gauge boson. The observables under investigation are the mixing related observables εK δMK, δMK, δMd/s and sin 2β, which we use to constrain the parameter space, as well as the rare decays K →, KL → and Bd/s → μ+μ-1. We find that significant effects are still possible in the K physics sector, while the B physics sector is already rather strongly constrained. The exception is the Bs - B-bar s mixing phase βs, which can be large
