Abstract
Using data from the FOCUS (E831) experiment at Fermilab, we present a new measurement for the branching ratios of the Cabibbo-suppressed decay modes D0 → π-π+ and D0 → K-K+. We measured: Γ(D0 → K-K+)/Γ(D0 → π-π+) = 2.81 ± 0.10(stat) ± 0.06(syst), Γ(D0 → K-K+)/Γ(D0 → K-π+) = 0.0993 ± 0.0014(stat) ± 0.0014(syst), and Γ(D0 → π-π+)/Γ(D0 → K-π+) = 0.0353 ± 0.0012(stat) ± 0.0006(syst). These values have been combined with other experimental data to extract the ratios of isospin amplitudes and the phase shifts for the D → K K and D → ππ decay channels.
