Description

Using 281 pb-1 of data collected with the CLEO-c detector, we present new measurements of Cabibbo-suppressed decays of D0 and D+ mesons to η and η' final states. We make first observations of D0→η'π0, ηη, ηη', and ηπ+π-, and find evidence for D+→ηπ+π0, D+→η'π+π0, and D0→η'π+π-. We also report on improved measurements of D0→ηπ0, D+→ηπ+, and D+→η'π+. Using the measured two-body Cabibbo-suppressed decays, we extract amplitudes for specific flavor topologies and compare them to those from Cabibbo-favored decays.
