Search for a Signal on Phase Transitions of Strongly Interacting Matter using the Nuclear Transparency Effect

We discuss that the results coming from the central experiments confirm the results which had been obtained for the behavior of the K+-meson's temperature behavior as a function of the energy in SPS energy range. To see the "horn" for the behavior of the ratio for average values of K+- to pi+- mesons as a function of centrality the new more rich experimental data are required. The data can be obtained with NICA/MPD setup. The existing of the QCD critical point could be identified by using the nuclear transparency effect as a function of the centrality.
