| description | Meson and anti-meson mixing processes constitute an important source of constraints on models that give tree level contributions to flavor violating neutral processes. In electroweak SU(3)L×U(1)N models, where anomaly cancellation requires that one family of quarks transforms differently from the other ones, processes involving flavor changing neutral currents gain tree level contributions mediated by gauge and scalar fields. Here, we firstly investigate the contributions of the neutral scalar that mimics the standard Higgs to the K0−K¯0, B0−B¯0, and D0−D¯0 mixing processes and confront our predictions with experiments. The results will determine the quark mixing matrices VLu,d. In possession of this information we, next, evaluate the contributions of the neutral gauge bosons Z′ and Z to the K0−K¯0, B0−B¯0, and D0−D¯0 processes. This realistic approach to meson transitions will provide severe bounds on MZ′ and Z−Z′ mixing angle. |
