Abstract
We report a measurement of the relative branching ratio of two Cabibbo -suppressed decay modes: D0 --> pi-pi+ 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 DO --> K-pi+ are also presented. The relative branching ratios are measured to be GAMMA(D0 --> KK)/GAM MA(D0 --> pipi) = 2.53 +/- 0.46 +/- 0.19, GAMMA(D0 --> KK)/GAMMA (D0 - -> Kpi) = 0.109 +/- 0.007 +/- 0.009, and GAMMA(D0 --> pipi)/GAMMA (D0 --> Kpi) = 0.043 +/- 0.007 +/- 0.003.
