| Research Abstract |
We studied several issues associated with experiments designed for testing nonlocality of quantum mechanics based on elementary particles including mesons. The problems for establishing quantum correlations due to the indistinguishablity of particles and their passive nature of decays were analyzed. We proposed a novel set of measures which is useful to characterize the entanglement of many particle states (such as GHZ and W). The intrinsic relative nature of entanglement with respect to measurement setups was also made transparent in our treatment of correlations.
