Resonating Two-body D DecaysperGronau, MichaelUSDOE Office of Energy Research (ER) (United States)orgUnited States. Department of Energy.

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.8 pagesAmplitudesFactorizationLow-Energy Theorem72 Physics Of Elementary Particles And FieldsDecay AmplitudesResonance
