Results for the Cabibbo suppressed semileptonic decays D0 → π-μ+v and D0 → π-μ+v (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(D0 → π-l+v)/BR(D0 → K-l+v) combined sample is measured to be 0.101 ± 0.020 (stat.) ± 0.003 (syst.) 14.
