The structure functions of the deuteron were calculated taking into account the single-particle current and the contribution of Fermi motion effects was investigated. Development of a program for calculating deuteron electromagnetic form factors taking into account meson exchange currents has begun. An analysis of the process of electron-positron annihilation is carried out taking into account the Lagrangian expansion of the interaction with terms responsible for the violation of CP-invariance. As a result of the research, an observable was discovered and analyzed, which is physically interpreted as a deviation of the average energies of the final bottom quarks. This difference was considered as a function of the invariant energy of the process when using different degrees of polarization of the initial electron and positron.
