Abstract

We report a measurement of the relative branching ratio of two Cabibbo-suppressed decay modes: D⁰ → π^-π⁺ and D⁰ → K^-K⁺. The data were accumulated in the 1990-1991 fixed target run of Fermilab high energy photoproduction experiment E687. The branching ratios of these modes relative to the Cabibbo-allowed decay D⁰ → K^-π⁺ are also presented. The relative branching ratios are measured to be Γ(D⁰ → KK)/Γ(D⁰ → ππ) = 2.53 ± 0.46 ± 0.19, Γ(D⁰ → KK)/Γ(D⁰ → Kπ) = 0.109 ± 0.007 ± 0.009, and Γ(D⁰ → ππ)/Γ(D⁰ → Kπ) = 0.043 ± 0.007 ± 0.003.
