Bose-Einstein correlations for mixed neutral mesons

Correlations are shown to arise in nonidentical mixed-particle pairs like k⁰k¯ ⁰ when observed in decay modes like k_sk_s in multiparticle final states containing many partial waves. No enhancement is found in any single partial wave. All partial wave analyses of s-wave threshold resonances a₀ and f₀ should give the same results for all decay modes. The effect may be useful in CP-violation experiments where B⁰-B¯ ⁰ pairs are inclusively produced and their Einstein-Podolsky-Rosen–correlated decays into ψK_S and leptonic modes are observed. The CP-violating lepton asymmetry is enhanced by a factor of 2 in the kinematic region where Bose enhancement occurs.
