First measurements of branching fractions for D_s^+ → K_S^0 K_S^0 π^+ π^0 and D_s^+ → K_S^0 K^+ π^0 π^0 are (4.08 ± 0.46 ± 0.45)×10^{-3} and (3.32 ± 0.64 ± 0.31)×10^{-3}.
Evidence at 3.6 sigma is reported for the semileptonic decays Lambda_c+ to Sigma^pm pi^mp e+ nu_e with branching fraction (7.7 +2.5 -2.3 stat +/- 1.3 syst) x 10^-4, consistent with quark-model predictions.
First absolute branching fraction measurements yield (3.81 ± 0.18stat ± 0.20syst)×10^{-4} for D0→γ K*0 and (2.51 ± 0.44stat ± 0.11syst)×10^{-5} for D0→γφ with 26.8σ and 7.9σ significance.
BESIII extracts branching fractions for ψ(3686)→p p-bar π⁰ and ψ(3686)→p p-bar η (two solutions each) and measures the N(1535) width ratio Γ(Nη)/Γ(Nπ) = 0.99 ± 0.05 ± 0.19 from partial-wave fits.
