Abstract

The relative branching fraction R_K = Γ(D⁰ → K^-μ⁺v)/Γ(D⁰ → μ^-X) has been measured by Fermilab experiment E653, using D⁰ mesons produced by 600 GeV π^-. The semimuonic decay sample of 232 events was identified by the decay chain D^*+ → D⁰π⁺, D⁰ → μ⁺h^-X, where h is a hadron. The Kμv component was extracted from the joint distribution of these events in the D⁰ decay variables M_min and p_Th. We find R_K = 0.472 ± 0.051 (stat) ± 0.040 (sys), and use a world average of the D⁰ → Klv branching fraction to obtain the D⁰ inclusive semimuonic branching fraction B(D⁰ → μ⁺X) = (7.67 ± 1.13)%.
