Symmetry, which is often viewed as a kind of beauty, is the most powerful idea in modern particle physics. Fundamental laws of the universe are governed by symmetries. Why is beauty truth? Yutaka was intrigued with this fact, even when he was undergraduate student. Since then, these types of deeper questions have been the driving force of his research.

Equally powerful is the idea of spontaneous symmetry breaking. If nature does not preserve whole symmetries of the laws, then the physicist says that the symmetry is spontaneously broken. Higgs particle is a key ingredient for the spontaneous symmetry breaking. Experiments to better understand the Higgs particle are currently being performed using the Large Hadron Collider at CERN. In this Hakubi project, Yutaka will focus on supersymmetry and try to construct a model for the early universe.
