Description

Relative phases of amplitudes for D meson decays to a light pseudoscalar meson P and a light vector meson V decaying to two pseudoscalar mesons will lead to characteristic interferences on the three-body Dalitz plot. These phases may be compared with predictions of a flavor-symmetric treatment which extracts contributing amplitudes and their relative phases from a fit to D→PV decay rates. Good agreement was found previously for the cases of B0→K+π-π0 and D0→π+π-π0. The present work is devoted to the decays D0→KSπ+π- and D0→π0K+K-, for which agreement is not found. Several suggestions are offered for this discrepancy.
