Inelastic Rescattering and CP Asymmetries in D -> pi+ pi-, pi0 pi0
X. Q. Li, B. S. Zou
Abstract
We study the direct CP violation induced by inelastic final state interaction (FSI) rescattering in Dππ modes, and find that the resultant CP asymmetry is about 10-4 which is larger than ε' in the K-system. Our estimation is based on well-established theories and experiment measured data, so there are almost no free parameters except the weak phase δ13 in the CKM matrix.
