Strangeness conservation and pair correlations of neutral kaons with close momenta produced in inclusive multiparticle processes

The phenomenological structure of inclusive cross sections of the production of two neutral K mesons in collisions of hadrons and nuclei is investigated taking into account the strangeness conservation in strong and electromagnetic interactions. The relations describing the dependence of the correlations of two short-lived and two long-lived neutral kaons K _S ⁰ K _S ⁰ , K _L ⁰ K _L ⁰ and the correlations of “mixed” pairs K _S ⁰ K _L ⁰ at small relative momenta upon the space-time parameters of the generation region of K ⁰ and mesons, which involve the contributions of Bose statistics and S-wave strong final-state interaction, have been obtained. It is shown that, under the strangeness conservation, the correlation functions of the pairs K _S ⁰ K _S ⁰ and K _L ⁰ K _L ⁰ , produced in the same inclusive process, coincide, and the difference between the correlation functions of the pairs K _S ⁰ K _S ⁰ and K _S ⁰ K _L ⁰ is conditioned by the production of the pairs of nonidentical neutral kaons K ⁰ .
