نویسنده
چکیده
A pair of B 0 ¯ B 0 mesons from Υ(4S) decay exhibit EPR type non-local particle-antiparticle (flavor) correlation. It is possible to write down Bell Inequality (in the CHSH form: S ≤ 2) to test the non-locality assumption of EPR. Using semileptonic B 0 decays of Υ(4S) at Belle experiment, a clear violation of Bell Inequality in particle-antiparticle correlation is observed: S = 2.725 ± 0.167stat ± 0.092syst .

We establish a relation between the Schwarz inequality and the generalized concurrence of an arbitrary, pure, bipartite or tripartite state. This relation places concurrence in a geometrical and functional-analytical setting.

In this paper we show that if the refractive index, or rather, [n(ω) − 1] satisfies the dispersion relations then, it is implied by Titchmarsh's theorem that, n(ω) → 1 as ω → ∞. Any other limiting value for n(ω) would violate relativistic causality, by which we mean not only that cause must precede effect but also that signals cannot travel faster–than–c, the velocity of light in a vacuum.
