description: Experiments studying the production of muon pairs in proton-nuclear collisions have shown non-exclusive particle production outside the allowable kinematic region. This effect can be explained by the presence of short-term low-nucleon correlations in the nuclei. In the production of particles on nuclei, the appearance of bound states is considered as a random correlation of the wave functions of nucleons called fluctons. Fluctons are quasiparticles and belong to baryons. In contrast to the collision of a proton with a nucleon of a nucleus, the collision with a flucton can go beyond the allowable kinematic region due to an additional momentum of the internal motion of the nucleons in the flucton. This work is devoted to the introduction of fluctons in the Monte Carlo generator PYTHIA 8. Using the methods described in it, it is possible to simulate the processes of cumulative particle production for future experiments, in particular for the NICA collider. In the course of the work done, a technique was developed and the process of introducing new particles (fluctons) into the Pythia high-energy physics software package was started. A method for simulating the kinematic features of fluctons similar to the introduction of additional Fermi motion of nuclei was developed and tested. The distribution of muon pairs over the invariant mass was also obtained. In addition, invariant cross sections of protons, antiprotons Ï +, Ïâ, K +, K â mesons and their ratios were obtained. In addition, the distribution of muon pairs over the invariant mass was obtained. The results were compared with experimental data.
