| Abstract | |
We show that final state interactions (FSI) within a CPT invariant two-channel framework can enhance the charge-parity (CP) violation difference between D-0 -> pi(-)pi(+) and D-0 -> K-K+ decays up to the current experimental value. This result relies upon (i) the dominant tree level diagram, (ii) the well-known experimental values for the D-0 -> pi(-)pi(+) pthorn and D-0 -> K-K+ branching ratios, and (iii) the pi pi -> pi pi and pi pi -> KK scattering data to extract the strong phase difference and inelasticity. Based on well-grounded theoretical properties, we find the sign and bulk value of the Delta A(CP) and A(CP)(D-0 -> pi(-)pi(+) recently observed by the LHCb Collaboration. (AU) | |
