BELL THEOREM WITHOUT THE HYPOTHESIS OF LO CALITY

One of the Bell's assumptions in this original derivation of the inequ alities was the locality one, i. e. the independence o two separated m easuring devices. That is why the Bell inequalities breaking, observed in the experiments, is often interpreted as a demonstration of nonloc al quantum mechanic features or the contradiction to the local realism . In this work a straightforward derivation of the Bell inequalities t raditional form is given, without appealing to locality, but based onl y on the assumption that the probability distributions is to be nonneg ative. The same probability distributions are calculated for the concr ete optical experiment under the quantum theory consideration, and it is shown that they can be negative. So, the irrelevance of the Bell in equalities breaking to the locality assumption is strictly proved. The physical nature of the obtained results is examined.
