Abstract :

Modern cosmology is based on the inflationary models with baryosynthesis and dark matter/energy. These cornerstones of the structure and evolution of the universe are well supported by the observational data of the precision cosmology but find no physical basis in the known physics. Such basis appears in physics beyond the standard model of elementary particles. The hope that supersymmetric extension of the standard model can not only provide physical grounds for the modern cosmology but also can find experimental verification at the Large Hadron Collider (LHC) is not supported by the negative results of searches for supersymmetric particles at the LHC. The simplest solution for dark matter candidates in the form of weakly interacting massive particles (WIMPs) in spite of its miraculous possibility to explain cosmological dark matter also doesn’t find support in experimental searches for dark matter. It makes us to extend the field of research of new physics, on which modern cosmology can be based. In many cases such extensions are related to super high energy physics, which cannot be studied directly in the experiments at modern and even planned particle accelerators. Cosmoparticle physics studying fundamental relationship of cosmology and particle physics in the proper combination of its indirect physical, astrophysical and cosmological signatures can offer the solution to approach the true physics, on which true cosmological structure and evolution is based. The methods of cosmoparticle physics and examples of probes for various predictions of new physics are discussed
