Abstract

We present measurements of the branching ratios for two Cabibbo suppressed decays of the D0 meson, D0 → π+π+π-π- and D0 → K-K+, and for the decay D+s → f{cyrillic}π+π+π-. The physics signals were extracted from a data sample consisting of 60 million triggers, collected by Fermilab Photoproduction Experiment E687 from December 1987 to February 1988. The relative branching ratios are measured to be: Γ(D0 → 4π)/Γ(D0 → K3π) = 0.108±0.024±0.008, Γ(D0 → KK)/Γ(D0 → Kπ) = 0.138±0.027 ±0.010 and Γ(Ds → f{cyrillic}3π)/Γ(Ds → f{cyrillic}π) = 0.58±0.20±0.10.
