Zusammenfassung:As the basic criterion of the validity of quantum mechanics, Bell's inequality has aroused wide theoretical and experimental interest. With the accumulation of an increasing number of events in high-energy physics, it is tempting to test Bell's inequality directly in particle physics. In this paper, we choose the P a VV decay to reveal entanglement between daughter particles. On the basis of quantum mechanics predictions in the literature, we present a statistical method that can fully utilize the data available. A Monte Carlo simulation was carried to study the effects of detector geometry, detector efficiency and momentum resolution.
