Abstract

Dalitz plot analyses of four Kππ decays of the D0 and D+ mesons are presented. The relative amounts of K̄*π, K̄ρ{variant} and non-resonant Kππ in each decay mode are determined, and isospin amplitudes and phases are derived. These results are compared with predictions from QCD. The K-π+π+ mode has a non-uniform, non-resonant contribution; attempts to fit this distribution are described.
