Exotic and Conventional Quarkonium Physics Prospects at Belle II

The Belle II experiment, now operating at the KEK laboratory in Japan, is a substantial upgrade of both the Belle detector and the KEKB $e^+ e^-$ accelerator. It aims to collect 50 times more data than existing B-Factory samples. Belle II is uniquely capable of studying the so-called "XYZ"particles: heavy exotic hadrons consisting of more than three quarks. First discovered by Belle, these now number in the dozens, and represent the emergence of a new category within quantum chromodynamics. This talk will present the capabilities of Belle II to explore both exotic and conventional quarkonium physics. On behalf of the Belle II Collaboration
