Abstract
A generalization of the CHSH-Bell inequality to arbitrary many settings is presented. The singlet state of two spin 1/2 violates this inequality for a ll numbers of setting. In the limit of arbitrarily large number of settings , the violation tends to the finite ratio 4/pi approximate to 1.27. (C) 199 9 Elsevier Science B.V. All rights reserved.
