Query: A global analysis of two-body D to VP decays within the framework of
  flavor symmetry   Two-body charmed meson decays $D\to VP$ are studied within the framework of
the diagrammatic approach. Under flavor SU(3) symmetry, all the flavor
amplitude sizes and their associated strong phases are extracted by performing
a $\chi^2$ fit. Thanks to the recent measurement of $D_s^+\to\pi^+\rho^0$, the
magnitudes and the strong phases of the $W$-annihilation amplitudes $A_{P,V}$
have been extracted for the first time. As a consequence, the branching
fractions of all the $D\to VP$ decays are predicted, especially those modes
that could not be predicted previously due to the unknown $A_{P,V}$. Our
working assumption, the flavor SU(3) symmetry, is tested by comparing our
predictions with experiment for the singly and doubly Cabibbo-suppressed decay
modes based on the flavor amplitudes extracted from the Cabibbo-favored decays
using the current data. The predictions for the doubly Cabibbo-suppressed
channels are in good agreement with the data, while those for the singly
Cabibbo-suppressed decay modes are seen to have flavor SU(3) symmetry breaking
effects. We find that the inclusion of SU(3) symmetry breaking in color-allowed
and color-suppressed tree amplitudes is needed in general in order to have a
better agreement with experiment. Nevertheless, the exact flavor
SU(3)-symmetric approach alone is adequate to provide an overall explanation
for the current data.
