Abstract:

This paper addresses the issue of checking Bell's inequalities in elementary particle physics. A new expression for the Bell inequality is proposed in terms of experimentally measurable angular observables. As an example, the degree of violation of the Bell inequality in the decays &\eta_c\to\Lambda\bar{\Lambda}, \chi_c\to\Lambda\bar{\Lambda} ; and &J/\psi\to\Lambda\bar{\Lambda} ; is studied.
