Xq. Li et Bs. Zou, INELASTIC RESCATTERING AND CP ASYMMETRIES IN D-]PI(-),PI(0)PI(0)()PI(), Physical review. D. Particles and fields, 57(3), 1998, pp. 1518-1523
We study direct CP violation induced by inelastic final state interact
ion rescattering in D --> pi pi modes, and iind that the resultant CP
asymmetry is about 10(-4) which is larger than epsilon' in the K syste
m. Our estimation is based on well-established theories and experiment
ally measured data, so there are almost no free parameters except the
weak phase delta(13) in the CKM matrix.
