论文摘要
我们表明，CPT不变的两通道框架中的最终状态相互作用（FSI）可以增强$ d^0 \toπ^-π^+$和$ d^0 \ to K^-k^-k^+$之间的违规差异（CP）违规差异。 This result relies upon: (i) the dominant tree level diagram, (ii) the well-known experimental values for the $D^ 0\toπ^-π^+$ and $D^ 0\to K^-K^+$ branching ratios, and (iii) the $ππ\to ππ$ and $ππ\to K K $ scattering data to extract the strong phase difference and inelasticity.基于良好的理论属性，我们发现$ΔA_{cp} $和$ a_ {cp}（d^0 \toπ^-π^+）$最近观察到的$ΔA_{cp} $的符号和大容量值。
We show that final state interactions (FSI) within a CPT invariant two-channel framework can enhance the charge-parity (CP) violation difference between $D^0\toπ^-π^+$ and $D^0\to K^-K^+$ 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 $D^ 0\toπ^-π^+$ and $D^ 0\to K^-K^+$ branching ratios, and (iii) the $ππ\to ππ$ and $ππ\to K K $ 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 $ΔA_{CP}$ and $A_{CP}(D^0 \to π^-π^+)$ recently observed by the LHCb Collaboration.
