Query: Maximal violation of Bell's inequality in the case of real experiments   Einstein's locality is invoked to derive a correlation inequality. In the
case of ideal experiments, this inequality is equivalent to Bell's original
inequality of 1965 which, as is well known, is violated by a maximum factor of
1.5. The crucial point is that even in the case of real experiments where
polarizers and detectors are non-ideal, the present inequality is violated by a
factor of 1.5, whereas previous inequalities such as Clauser-Horne-Shimony-Holt
inequality of 1969 and Clauser-Horne inequality of 1974 are violated by a
factor of $\sqrt 2$. The larger magnitude of violation can be of importance for
the experimental test of locality. Moreover, the supplementary assumption used
to derive this inequality is weaker than Garuccio-Rapisarda assumption. Thus an
experiment based on this inequality refutes a larger family of hidden variable
theories than an experiment based on Garuccio-Rapisarda inequality.
