Improving theoretical ideas of hadron interaction dynamics and fundamental properties of strongly-interacting matter

popup.description2

Phenomenological models for the state equation of pion matter for non-zero values of the electric chemical potential have been constructed. Fluctuations in the number of particles were calculated using molecular dynamics with the Lennard-Jones potential. The acceptance procedure of binomial data on the normalized variation, asymmetry, and excess of the proton number distribution measured by the HADES collaboration was described. The uniqueness of the FMO-model is shown, and a modification of the model with fewer free parameters is found. Recalculations are performed to compare this model with other models and experimental data on elastic scattering of protons and antiprotons. The analytical and Monte-Carlo numerical calculations were performed in lattice models for finite chemical potentials. The t'Hooft-Veneziano limit of the Polyakov loop models is developed. It is calculated 2- and N-point correlation functions and the behaviour of screened masses in the confinement and deconfinement regions.
