The Belle II detector at the SuperKEKB accelerator complex at KEK will probe new physics at energy scales beyond the reach of the LHC. By examining flavor changing processes of subatomic particles produced in e+e－ collisions it will look to solve some of the remaining mysteries of the universe:the striking mass and coupling hierarchy of elementary particles, fundamental sources of matter-antimatter asymmetries, dark matter, and how neutrinos got a mass. New interactions and yet unseen particles must exist to explain these phenomena. In this seminar, I shall discuss the physics behind the Belle II experiment at SuperKEKB, and what we hope to achieve by charting this intensity frontier.
