Description
The Higgs boson was discovered in the LHC experiment, but given the current lack of physics beyond the Standard Model of particle physics, such as supersymmetry, the importance of the universe as a means of exploring more fundamental laws of physics at high energies is expected to increase. In more fundamental theories beyond the Standard Model, it is believed that many new particles exist in addition to those of the Standard Model, but their mass scales are, of course, unknown. Although particles on the order of a few TeV may be found in the near future using ground-based accelerators, it will be almost impossible to directly produce particles with masses far beyond the TeV scale using ground-based accelerators even in the future. Therefore, the only way to elucidate the nature of such new particles is to look for their traces in the universe. In this talk, we will explain how to extract information about physics beyond the Standard Model through the properties of primordial density perturbations produced during inflation.
