Bell nonlocality
read the original abstract
Bell's 1964 theorem, which states that the predictions of quantum theory cannot be accounted for by any local theory, represents one of the most profound developments in the foundations of physics. In the last two decades, Bell's theorem has been a central theme of research from a variety of perspectives, mainly motivated by quantum information science, where the nonlocality of quantum theory underpins many of the advantages afforded by a quantum processing of information. The focus of this review is to a large extent oriented by these later developments. We review the main concepts and tools which have been developed to describe and study the nonlocality of quantum theory, and which have raised this topic to the status of a full sub-field of quantum information science.

Bell nonlocality and entanglement in $\chi_{cJ}$ decays into baryon pair
Chi_c0 decays exhibit maximal Bell violation and entanglement, chi_c1 shows angle-modulated violation, and chi_c2 baryon pairs are separable with no violation.
