On the violation of the CHSH network model inequality
  In the present paper it is demonstrated that the quantum correlation (2-dim unitary parameter vectors) can be arbitrarily close approximated with a local hidden variables model. Moreover, the CHSH inequality can be violated with the present model. This does not conclusively demonstrate that locality and causality can be restored to quantum mechanics. However, it does show that an experimental search for local hidden causality need not be fruitless beforehand.
