A minimal abelian extension of the SM is considered, based on the introduction of a new massive, neutral gauge boson Z′. Due to the specific solution adopted for the cancellation of gauge anomalies, the new mediator has flavor non-universal couplings to quarks and leptons.

As a result, quark and lepton sectors constrain each other to prevent large deviations from SM predictions. Moreover, correlations emerge between quark flavor and lepton flavor violating processes, such as lepton flavor violating B meson and purely leptonic decays. In this seminar, after reviewing the motivations and strategies for the search of BSM physics, the key aspects and predictions of this model for rare and SM-forbidden decays will be presented.
