“…[93], the BESIII Collaboration studied the e + e − → γX(3872) process and measured the product of the cross section σ(e + e − → γX(3872)) and the branching ratio B(X(3872) → π + π − J/ψ) at center-of-mass energies 4.009, 4.229, 4.26 and 4.360 GeV, which hinted the existence of the Y(4260) → γX(3872) radiative decay.

In the past decade many charmonium-like states were observed experimentally. Especially those charged charmoniumlike Z c states and bottomonium-like Z b states can not be accommodated within the naive quark model. These charged Z c states are good candidates of either the hidden-charm tetraquark states or molecules composed of a pair of charmed mesons. Recently, the LHCb Collaboration discovered two hidden-charm pentaquark states, which are also beyond the quark model. In this work, we review the current experimental progress and investigate various theoretical interpretations of these candidates of the multiquark states. We list the puzzles and theoretical challenges of these models when confronted with the experimental data. We also discuss possible future measurements which may distinguish the theoretical schemes on the underlying structures of the hidden-charm multiquark states.

“…X(3872), the well-known one of the XY Z particles [77], is supposed to χ ′ c1 state or the mixture of this state with other structure in some view [49,78]. Recently, X(3872) has been observed in photon-recoiled process with a statistical significance of 6.4σ at BESIII [79]. X(3915) (X(3945) or Y (3940)) and Z(3930) are assigned as χ c0 (2P ) and χ c2 (2P ) states by the Particle Data Group (PDG) [80], however this identification may call into some questions [81].…”

Abstract. Hadron spectroscopy is one of the most important physics goals of BESIII. BESIII brings great opportunities to study the XYZ states of charmonium by directly producing the Y states up to 4.6 GeV. High statistics of charmonium decays collected at BESIII provide an excellent place for hunting gluonic excitations and studying the excited baryons. Recent results of light hadron spectroscopy and charmonium spectroscopy from BESIII will be reported.
