The very fundamental particles found in nature are leptons (electrons and their charged cousins, and neutrinos) and quarks. The Standard Model (SM) describes how these interact via the strong and electroweak forces. Our group studies neutrinos which have puzzling behavior unexplained by the Standard Model; we also study the nature of the SM forces, with emphasis on searches for new phenomena that may lie beyond.

In particular, we focus on

  • Studies of particles that contain the bottom and charm quarks; such decays may provide evidence of fundamentally new particles or sources of CP symmetry violation. This and other fundamental research is conducted using data collected by the Belle and Belle II experiments at KEK in Japan.
  • Further studies of neutrino physics.
