Registration Date 29-01-2026 Organization National Science Center "Kharkiv Institute of Physics and Technology" popup.description1 The main objective of the work is to improve and expand fundamental knowledge in nuclear physics, particle physics and high-energy physics, astrophysics, and cosmology, which could influence the development of alternative methods of theoretical description and the advancement of cutting-edge technologies in condensed matter physics, quantum optics, interferometry, and modern communication systems. Calculations of differential cross-sections and polarization observables in the processes e+e- → NNbar pi, taking into account the contributions of intermediate vector mesons and resonances with spins 1/2 and 3/2, as well as their interference with non-resonant backgrounds. Develop a theoretical description of electron-positron annihilation, considering CP violation effects, polarization of initial beams, spin correlations, and BSM contributions. Construct analytical expressions for new observables sensitive to the electric dipole moment of the top quark, focusing on future experiments at ILC and CLIC colliders. Create a theoretical and numerical description of electron-positron pair production by a photon or electron in the field of an intense plane electromagnetic wave (laser), predict their characteristics, and compare the results with experimental data. Study the properties of nuclei across a wide range of mass numbers and the manifestation of octupole deformations in even-even nuclei in the rare-earth region, including nuclei with a significant neutron excess, within the Hartree-Fock-Bogoliubov approximation. Conduct a review of the main cosmological models, incorporating current observational data, and propose alternative models beyond the Standard Cosmological Model. Show that quantum entangled states between microscopic degrees of freedom play a significant role in explaining the thermodynamic properties of black holes. popup.nrat_date 2026-01-29 Close
