WeakD→Kπdecays revisited

Soft theorems of current algebra are consistently applied to D→Kπ decay amplitudes from which $D^{\mathrm{*}}$, $F^{\mathrm{*}}$, and $K^{\mathrm{*}}$ pole contributions have been removed. The $K^{\mathrm{*}}$ pole, ignored in previous calculations, represents the contribution of the flavor annihilation channel. The net effect is an improved, though not entirely satisfactory, understanding of D→Kπ data, with real amplitudes. Final-state interactions are introduced to give a fit to data.
