A relevant two qubit Bell inequality inequivalent to the CHSH
... We are interested in the faces of the convex set in this reduced space. These are ‘tight’ inequalities. There are of course other inequalities which are satisfied by all the points inside the past-generated set, but such inequalities are less useful for detecting non-local correlations. An inequalit ...

... The Pomeron couples with the same strength to the proton and antiproton because the Pomeron carries the quantum numbers of the vacuum. The Regge trajectory can have different couplings to particles and antiparticles. This accounts for the difference between the p p and p p cross-sections at lo ...
