Description
The Belle II experiment at the SuperKEKB electron–positron collider provides a high-luminosity environment uniquely suited for precision studies of hadron physics. Although primarily designed for flavor physics, Belle II offers powerful opportunities to address key questions in non-perturbative QCD that are of direct interest to nuclear physics.
In this talk, I will present recent Belle II measurements and near-term prospects relevant to hadron spectroscopy, hadronization, and the internal structure of hadrons.
Belle II measurements of exotic hadron candidates provide improved information on masses, widths, quantum numbers, and decay modes.
Analyses of semi-inclusive hadron production in electron–positron annihilation yield differential cross sections, azimuthal asymmetries, and transverse-momentum distributions that can directly constrain TMD fragmentation functions and spin–momentum correlations.
Furthermore, Belle II measurements of meson and baryon time-like electromagnetic form factors can probe hadron structure in a kinematic regime complementary to space-like experiments.
These existing and future results demonstrate the capability of Belle II to deliver high-impact hadron-structure measurements and its complementarity with ongoing and future nuclear physics experiments.
