Description
Summary:In the past 20 years,many new hadrons that are difficult to explain within the conventional quark model have been discovered in the quarkonium region;these are called exotic hadrons.The Belle Ⅱ experiment,as the next-generation B factory,provides a good platform for exploring 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 production.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 newYbstates with JPC=1--,Xb[the bottom counterpart of xc1(3872),also known as X(3872)]and partners of Zb states.We give a mini-review on the status and prospects of exotic hadrons at Belle Ⅱ.
