Description
Hyperon-antihyperon pairs produced in high energy electron-positron annihilation are promising systems for the study of quantum information properties. We make an analysis of some types of quantum correlations, Bell nonlocality, quantum steering and discord, in hyperon-antihyperon systems produced in electron-positron annihilation through J/\psi decay. The behaviors of these quantum correlations differ from those in elementary particle-antiparticle systems such as the top quark and tau lepton due to the polarization effect. The hierarchy of quantum correlations is examined and partially confirmed in hyperon-antihyperon systems: Bell Nonlocality \subset Steering \subset Entanglement. We also investigate the effect of the electromagnetic form factors of hyperons on four types of quantum correlations.
