Physics reach of D(s) π(K) and other charming null test opportunities

Abstract

We discuss possibilities to test physics beyond the Standard Model in c= u= 1 semileptonic, hadronic and missing energy decay modes. Clean null test observables such as angular observables, CP-asymmetries and lepton universality tests are presented and model-independent correlations as well as details within flavorful, anomaly-free Z models are worked out.
