【 摘 要 】

The phenomenological structure of inclusive cross-sections of the production of two neutral K mesons in collisions of hadrons and nuclei is studied taking into account the strangeness conservation in strong and electromagnetic interactions. Expressions for the correlation functions are obtained. It is shown that the correlation functions of the pairs KosKosand K°LK°L, produced in the same inclusive process, coincide, and the difference between those for the pairs K°SK°Sand K°SK°Lis conditioned by the generation of pairs of non-identical kaons K°K°. Analogous pair correlations for neutral heavy mesons D°, B°and B°sare also analyzed.
