The physical characteristics and chemical composition of galaxies, in particular the carbon content, were determined. Within the framework of the model of dark matter (TM) as a self-gravitating Bose–Einstein condensate (BEC), it is shown that the axion-like self-action of ultralight bosons ensures the existence of both rarefied and dense phases in the cores of the TM halo (dwarf) galaxies. It is proposed to choose the standard pomeron and odderon with linear trajectories and single intercepts in the model as satisfying the maximization principle of the strong interaction. A defect with violation of unitarity in the crossing of the odd component of the amplitude, the contribution of Froissart and Maximum Odderon has been fixed. Amplitudes of elastic scattering were calculated using a method that will be useful for taking into account corrections at high energies. A prediction was obtained for the diffraction dissociation of protons and antiprotons at the energies of the LHC accelerator at CERN. It is shown that the spectrum of resonant states predicted by Hagedorn half a century ago also depends on the (nonlinear, complex) Regge trajectories of this family, or rather their derivatives. A canonical ensemble of non-interacting bosons in local equilibrium is considered. The resulting expressions were applied to the numerical calculation of correlation functions in a system with parameters that are typical for proton-proton collisions at the Large Hadron Collider (LHC).
