    "abstract": "We analyze and compare the mathematical formulations of the criterion for\nseparability for bipartite density matrices and the Bell inequalities. We show\nthat a violation of a Bell inequality can formally be expressed as a witness\nfor entanglement. We also show how the criterion for separability and a\ndescription of the state by a local hidden variable theory, become equivalent\nwhen we restrict the set of local hidden variable theories to the domain of\nquantum mechanics. This analysis sheds light on the essential difference\nbetween the two criteria and may help us in understanding whether there exist\nentangled states for which the statistics of the outcomes of all possible local\nmeasurements can be described by a local hidden variable theory.",
