Measurement of exclusive D meson decays to eta and eta' final states and SU(3) amplitude analysis

Abstract

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 eta and eta' final states. We make first observations of D0-->eta'pi0, eta eta, eta eta', and eta pi+ pi-, and find evidence for D+ --> eta pi+ pi0$, D+ --> eta' pi+ pi0 and D0 --> eta' pi+ pi-. We also report on improved measurements of D0-->eta pi0, D+ --> eta pi+ and D+ --> etap' pi+. Using the measured two-body Cabibbo-suppressed decays, we extract amplitudes for specific flavor topologies and compare them to those from Cabibbo-favored decays.
