Analysis of search paths and prospects in experiments on particle colliders outside the SM or obtaining restrictions on their parameters. Study of astrophysical manifestations of supermassive particle decays in SM expansions. Investigation of the effects of modified gravity in the theory of dark matter and in models of isolated space systems. popup.description2 The Standard Model (SM) of particle physics describes with high accuracy the known elementary particles and the processes of electromagnetic, weak and strong interactions between them, but does not explain a number of problems (dark matter (TM), etc.), therefore it requires expansion. We will study detectors-observatories of multichannel astronomy. In extensions of the SM with particles with a mass of several GeV, new vector bosons with Chern-Simons-type interactions will be investigated and the sensitivity region of high-luminosity experiments to the search for these particles at colliders will be calculated. In extensions of the SM to energies of the order of TVO (1025 eV), astrophysical manifestations of decays of supermassive particles generated by cosmic string cusps and decays/annihilations of TM particles will be investigated. In the scalar-gravitational sector of the SM expansion, the manifestations of TM particles with masses in the range from meV to MeV, as well as astrophysical manifestations of scalar fields, will be studied. The goal of the project is to develop new models and search for observational manifestations of physics beyond the SM in ground-based laboratories and in space conditions, analyze the ways and prospects of searching for particles beyond the SM in collider experiments or obtaining constraints on their parameters, study astrophysical manifestations of decays of supermassive particles in SM expansions and the effects of modified gravity in the theory of dark matter and in models of isolated space systems.  Product Description popup.authors Babur Valentyna М.
