Frabetti, P. L.

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 .
