Observation of Bell Inequality violation in B mesons

Abstract

A pair of $B^0{\bar{B}}^0$ mesons from ${\rm Y}(4S)$ decay exhibit EPR type non-local particle-antiparticle (flavor) correlation. It is possible to write down Bell Inequality (in the CHSH form: $S\le 2$) to test the non-locality assumption of EPR. Using semileptonic $B^0$ decays of ${\rm Y}(4S)$ at Belle experiment, a clear violation of Bell Inequality in particle-antiparticle correlation is observed: S=2.725+-0.167(stat)+-0.092(syst)
