Resonating Two-body D Decays
The contribution of a K*(1430) 0{sup +} resonance to D{sup 0} {yields} K{sup -} {pi}{sup +} is calculated by applying the soft pion theorem, and is found to be about 20% of the measured amplitude and to be larger than the {Delta}I = 3/2 component of this amplitude. We estimate a 50% contribution to the total amplitude from a higher K*(1950) resonance. This implies large deviations from factorization in D decay amplitudes, and an enhancement of D{sup 0}-{bar D}{sup 0} mixing due to SU(3) breaking.
