Our group is participating in the international Belle II experiment, which analyzes lepton collisions produced by SuperKEKB in Japan. This collider is the most intense in the world. We study the flavor changes between quarks to discover new processes not described by the standard model of particle physics. In particular, we focus on measurements sensitive to additional sources of CP symmetry violation that could explain the disappearance of antimatter in the universe, and we test the fundamental principle of lepton universality, which has recently been challenged by several measurements.
We are also working on the Belle II silicon detector, the closest to the collision and one of the most accurate in the field, and on the development of the next generation of such detectors equipped with CMOS pixel sensors.
