Effects beyond the Standard model of elementary particles have been searched for: dark matter, sterile neutrinos, axions, non-conservation of electric charge. The studies were carried out using low-background scintillation, semiconductor, cryogenic detectors, a time-proportional chamber filled with argon in the gas and liquid phases. The double beta decay of 48Ca, 94Zr, 100Mo, 96,102Ru, 106,116Cd, 136,138Ce, 180W, 184,192Os nuclei was investigated at a new sensitivity level, the half-lives of 48Ca, 100Mo, 116Cd, 150Nd nuclei with a new accuracy level were measured with respect to the two-neutrino decay mode. For the first time search for fourfold beta decay has been performed. Neutrino fluxes from the Sun and from the depths of the Earth were measured. The half-life of the 212Po nucleus was refined. Searches for superheavy nuclei have been carried out. Emission of electron-positron pairs in the alpha decay of the 241Am nucleus was studied. The results of the development of new materials for scintillation and cryogenic detectors are presented, including isotope-enriched materials promising for use in large-scale projects to search for neutrinoless double beta decay at the sensitivity level corresponding to the inverse scheme of neutrino mass states.
