The object of investigation is collisions of high energy hadrons, heavy particles beyond the Standard Model, the quark-gluon plasma, lattice models of quantum field theory. The purpose of the research is development of new mathematical methods and programs that meet the needs of the current Large Hadron Collider experiments and new generation experiments. The Abelian Z'-boson decay width in the model-independent approach is calculated. Restrictions on the Z'-boson couplings corresponding to the narrow resonance approximation are obtained. It is shown for the first time that the current experimental constraints on the decay width of the Standard-Model Z-boson do not impose any requirements for the Z' width. New restrictions on Z-Z' mixing angle are obtained. The various Z' couplings with light fermions are estimated. The equation of mesophase transitions line in supercritical region of a generalized thermodynamic system is derived. The relation between the critical exponents of thermodynamic coefficients of stability is established, and we study in which manner this relation changes with the type of system state equation. The color structure of the gluon field magnetic mass is investigated in the lattice SU(2) gluodynamics. The interaction between a monopole-antimonopole string and external neutral Abelian chromomagnetic field flux is considered. It is shown that the presence of the Abelian field flux weakens the screening of the string field. The obtained theoretical results are essential for understanding the modern scientific worldview and can be used in the processing of present and future colliders experimental data. Field of application – theoretical physics, high energy physics, nuclear physics, particle physics. Product Description popup.authors Galdina Olexandra M. Lyagushyn Sergiy F. Minaiev Pavlo Ye.
