As a result, numerical calculations of the wave functions of triton and helium-3 will be performed, and the influence of off-shell effects will be studied. Another goal of the work is to develop a theoretical description of the scattering of fast charged particles on targets of complex structure. As a result, it is planned to obtain a differential cross-section of particle scattering on a multilayer nanotube in the eikonal approximation of quantum electrodynamics for different orientations of the nanotube relative to the incident particle. In addition, the aim is to develop a theoretical approach to the analysis of electron-positron annihilation processes with polarized beams, in particular for constructing energy observables sensitive to CP-violation. The quantities reflecting the change in the average energy and energy asymmetry of bottom quarks upon inversion of beam polarizations are considered, which allows us to detect interference effects caused by the terms of new physics. The obtained results can serve as a theoretical basis for future experimental tests at the new generation of electron-positron colliders. popup.nrat_date 2025-07-03 Close
