model, the polarization parameter agrees with the SM-like partner decay D+ → K1 (→ Kππ)γ up to U-spin breaking corrections. The existence of partner decays allows to construct a null test which does not require [...] discussed. Based on the approximate SU(3)F symmetry of QCD as well as its subgroups, relations between partner decays are worked out. Branching ratios, CP asymmetries as well as the photon polarizations are …
