Description
The phenomenological structure of inclusive cross-sections of the
production of two neutral K mesons in hadron--hadron, hadron--nucleus
and nucleus--nucleus collisions is investigated taking into account the
strangeness conservation in strong and electromagnetic
interactions. Relations describing the dependence
of the correlations of two short-lived and two long-lived neutral kaons
$K^0_S K^0_S$, $K^0_L K^0_L$ and the correlations of "mixed" pairs
$K^0_S K^0_L$ at small relative momenta upon the space-time parameters
of the generation region of $K^0$ and $\bar{K}^0$ mesons
have been obtained. These relations involve the contributions
of Bose-statistics and S-wave strong final-state interaction of two
$K^0$ ($\bar{K}^0$)-mesons as well as of a $K^0$-meson with
a $\bar{K}^0$-meson, and also the contribution of transitions
$K^+ K^- --> K^0 \bar{K}^0$, and they depend upon the
relative fractions of produced pairs
$K^0 K^0$, $\bar{K}^0 \bar{K}^0$ and $K^0 \bar{K}^0$.
It is shown that under the strangeness
conservation the correlation functions of
the pairs $K^0_S K^0_S$ and $K^0_L K^0_L$, produced in the same
inclusive process, coincide, and the difference between the
correlation functions of the pairs $K^0_S K^0_S$ and $K^0_S K^0_L$
is conditioned exclusively by the production of the pairs of non-identical
neutral kaons $K^0 \bar{K}^0$. Analogous correlations for the pairs
of neutral heavy mesons $D^0$, $B^0$ and $B_s^0$, generated in
multiple processes with the charm (beauty) conservation, are analyzed,
and differences from the case of neutral K mesons are discussed .
