Abstract
The quasi-spin entanglement of neutral mesons to test the Bell nonlocality is systematically studied in the case of CP violation. The violation of Bell inequality in the oscillations of , , and meson pair systems are found at certain evolution time including the latest experimental data. Our study is helpful for studying CP-violating involved flavor entanglement and testing Bell inequality violation in the current and future high energy experiment facilities.
