  In this presentation I report on the results of the paper we published
recently together with Kacper Zalewski. It exploits the consequences of the
observation that the hadrons, being the composite objects, cannot be produced
too close to each other and thus must be correlated in space-time. One of these
consequences, which we discuss here, is that the correlation function need not
be larger than 1 (as is necessary if the space-time correlations are absent).
Since the data from LEP and from LHC do show that the correlation function
falls below 1, the particles must be correlated and we show that our
observation does explain this unexpected effect.
