Abstract Results for the Cabibbo suppressed semileptonic decays D 0 → π − e + ν and D 0 → π − μ + ν (charge conjugates are implied) are reported by Fermilab photoproduction experiment E687. We find 45.4 ± 13.3 events in the electron mode and 45.6 ± 11.8 in the muon mode. The relative branching ratio BR (D 0 →π − l + v) BR (D 0 →K − l + v) for the combined sample is measured to be 0.101 ± 0.020 (stat.) ± 0.003 (syst.) 14 .

Abstract We report on the first statistically significant observation of the vector meson Cabibbo suppressed semileptonic decay D+ → ρ0μ+ν. We measure the branching ratio of the decay mode D+ → ρ0μ+ν (plus possible unobserved γ from D+ → η′μ+ν, η′ → γρ0) with respect to the decay mode D + → K ∗0 μ + ν to be BR (D + → ρ 0 μ + ν) BR (D + → K ∗0 μ + ν) = 0.079 ± 0.019 ( stat ) ± 0.013 ( syst ) . Data were collected by Fermilab photoproduction experiment E687.
