Near the end of the last century, remarkable progress was made in elementary particle physics both experimentally and theoretically, which led to the development of the Standard Model. However, we consider the model as a realization of a more fundamental theory at low energies, since there are so many unexplained physics in the model. Now, elementary particle physics is entering an exciting period in which a new paradigm of the field will be opened by the new discoveries expected in experiments at high-energy frontier colliders. The Higgs boson and supersymmetry are the main targets in these experiments. In parallel to energy frontier physics, experimental and theoretical studies attack the mystery of quark and lepton flavors. The combined efforts in cosmology and particle physics give synergy effects in understanding the history and the current state of the Universe.
