“…However, there are still some data (see Table 1) not analyzed and data at more energy points will be taken. 104 More analyses with these data samples will allow many improved understanding of the XYZ states, especially the X(3872), Y (4260), Z c (3900), and Z c (4020). BEPCII is upgrading the maximum c.m.…”

The BESIII and the LHCb became the leading experiments in the study of the exotic states after the Belle and BaBar experiments finished their data taking in the first decade of this century. We review the progress in the study of the XYZ states at BESIII and LHCb experiments with their unique data samples in e + e − annihilation at center-of-mass energies of 3.8-4.6 GeV and in pp collision at center-of-mass energies 7, 8, and 13 TeV, respectively. With these data samples, we have deepened our understanding of the most famous charmonium-like states X(3872), Y (4260), Zc(3900), and Zc (4430), as well as other similar states like the Y (4140) and X(3823). We review the progress in the study of these states, and also discuss perspectives at future experiments.

“…Heavy-quark physics has evolved into a new phase. Charmonium-like states, which are known as XYZ states [1][2][3][4][5][6][7][8][9][10][11][12][13] and quite possibly exotic ones, conventional bottomonia including the lowest-lying state η b [14][15][16][17][18][19][20], and heavy pentaquark states [21] have been newly reported by various experimental collaborations (see also recent reviews [22][23][24][25]). These novel findings of heavy hadrons have renewed interest in heavy-quark spectra and have triggered subsequently a great deal of experimental and theoretical work (see for example the following reviews [26][27][28][29][30]).…”

Instanton effects on the heavy-quark static potential

We investigate the instanton effects on the heavy-quark potential, including its spin-dependent part, based on the instanton liquid model. Starting with the central potential derived from the instanton vacuum, we obtain the spin-dependent part of the heavy-quark potential. We discuss the results of the heavy-quark potential from the instanton vacuum. We finally solve the nonrelativistic two-body problem, associating with the heavy-quark potential from the instanton vacuum. The instanton effects on the quarkonia spectra are marginal but are required for quantitative description of the spectra.

We report the progress in the study of the exotic hadrons, also called XYZ states, at BESIII experiment with its unique data samples in e+ e− annihilation at center-of-mass energies of 3.8–4.6 GeV. The talk covers the observation of the Zc(3900) and Zc(4020) and new measurements related to them; updated measurement of the resonant parameters of the Y(4260) in e+ e−→ π+π− J/ψ and discovery of its new decay modes π+π−ψ(2S), ωχc0, π+π−hc, and D0D∗−π++c.c.; and observation of X(3872) in e+e− annihilation.
