Status and Prospects of Exotic Hadrons at Belle II

In the past twenty years, many new hadrons that are difficult to be explained within the conventional quark model have been discovered in the quarkonium region, which are called exotic hadrons. Belle II experiment, as the next-generation B factory, provides a good platform to explore them. The charmonium-like states can be produced at Belle II in several ways, such as B meson decays, initial-state radiation processes, two-photon collisions, and double charmonium productions. The bottomonium-like states can be produced directly in e + e - colliding energies at Belle II with low continuum backgrounds. Belle II plans to perform a high-statistics energy scan from the BB threshold up to the highest possible energy of 11.24 GeV to search for new Yb states with JPC = 1--, Xb (the bottom counterpart of χ c1(3872) (also known as X(3872))), and partners of Zb states. In this paper, we give a mini-review on the status and prospects of exotic hadrons at Belle II.

The Belle II experiment offers unique possibilities for discovering and interpreting exotic multiquark bound states to probe the fundamentals of QCD. We present recent results obtained on a unique data set collected at energies above the Υ(4𝑆), including searches for the hidden bottom transition between Y(10750) and 𝜒 𝑏𝐽 (1𝑃) and the measurement of the energy dependence of the 𝑒 + 𝑒 − → 𝑏𝑏 cross section.

We present the measurement of the energy dependence of the cross sections 𝜎(𝑒 + 𝑒 − → 𝜔𝜒 𝑏𝐽 (1𝑃)) [14], and the comparison with the analogous measurement by Belle at a higher centerof-mass energy [15]. The reconstruction of the 𝜔 𝜒 𝑏𝐽 (1𝑃) final state is fully exclusive.…”
