is known that a classical theory formulated in terms of a hidden variables satisfying reasonable condition of locality, yields predictions which are different from those of quantum mechanics. These predictions were casted into the form of inequalities which any realistic local theory must obey. Bell inequalities have been formulated for mesoscopic multi-terminal conductors in Refs. [@kawabata00; @chtchelkatchev02; @samuelsson03] in terms of electrical noise correlations at different terminals [@footnote2]. A test of quantum mechanics through Bell inequalities in mesoscopic physics is very challenging and most probably it would be rather difficult, if not impossible, to get around all possible loopholes. Although solid state systems are not the natural arena where to test the foundations of quantum mechanics, it is nevertheless very interesting to have access, manipulate and quantify these non-local correlations.

In this work we derive a Bell inequality for the full electron counting statistics and discuss its properties. The formulation we follow is based on what is known as the Clauser-Horne (CH) inequality [@clauser74; @mandel95]. We shall show that the joint probabilities for a given number of electrons to pass through a mesoscopic conductor (in a given time) should satisfy, for a classical local theory, an inequality.
