Analyses of heavy mesons and baryons hadronic charmless decays using the flavor SU(3) symemtry can be formulated in two different forms. One is to construct the SU(3) irreducible representation amplitude by decomposing effective Hamiltonian, and the other is to draw the topological diagrams. In the flavor SU(3) limit, we study various B/D → P P, V P, V V , B c → D P/DV decays, and two-body nonleptonic decays of beauty/charm baryons, and demonstrate that when all terms are included these two ways of analyzing the decay amplitudes are completely equivalent. Furthermore we clarify some confusions in drawing topological diagrams using different ways of describing beauty/charm baryons.

We report the first observation of D + → τ + ντ with a significance of 5.1σ. We measure B(D + → τ + ντ ) = (1.20 ± 0.24stat. ± 0.12syst.) × 10 −3 . Taking the world average B(D + → µ + νµ) = (3.74 ± 0.17)×10 −4 , we obtain R τ /µ = Γ(D + → τ + ντ )/Γ(D + → µ + νµ) = 3.21±0.64stat. ±0.43syst., which is consistent with the Standard Model expectation of lepton flavor universality. Using external inputs, our results give values for the D + decay constant f D + and the CKM matrix element |V cd | that are consistent with, but less precise than, other determinations.
