In particle physics, there are an established model describing all particle interactions we can observe on the earth, the Standard Model. However, there are several problems in the Standard Model. Among them I am focusing on existence of the dark matter and the hierarchy problem in the Higgs sector. Both problems suggests the existence of the new particles around the TeV scale. The Large Hadron Collider is the best place for directly probing the new physics at the TeV scale and the future upgrade options are also discussed. In particular, I focus on top partner searches at the LHC with the top tagging algorithm based on jet substructures.
