“…The authors of Refs. [205,243,467] noticed that it is not so easy to accommodate Z c (3900) as an isovector DD * molecular bound state, which is supported by several Lattice studies [468,469,470,471]. Prelovsek and Leskovec searched for the Z c (3900) on the lattice in the channel with J PC = 1 +− and I = 1 without success [468].…”

“…In Ref. [471], the low-energy scattering of the D * D * meson system was studied by Chen et al by Lattice QCD calculation. Their results indicated a weak repulsive interaction between the two vector charmed mesons, and did not support a bound state in this channel corresponding to the Z c (4020)/Z c (4025).…”

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.

“…Then, building two-meson operators in these corresponding channels with the right quantum numbers will allow us to explore the problem within this single-channel approximation. CLQCD had estimated the effects of other operators/channels, making sure that they do not ruin the major channel correlators [64,65]. Partially twisted boundary conditions have been utilized to fully explore the near threshold region.…”

I review some of the lattice results on spectroscopy and resonances in the past years. For the conventional hadron spectrum computations, focus has been put on the isospin breaking effects, QED effects, and simulations near the physical pion mass point. I then go through several singlechannel scattering studies within Lüscher formalism, a method that has matured over the past few years. The topics cover light mesons and also the charmed mesons, with the latter case intimately related to the recently discovered exotic XY Z particles. Other possible related formalisms that are available on the market are also discussed. 34th annual International Symposium on Lattice Field Theory

“…In the charmonium sector there have been a number of lattice QCD investigations [13][14][15]35,51,52,[59][60][61] and there have been a couple in the bottom sector [36,37]. However, the calculations are somewhat less advanced than in the other sectors and studies have generally been exploratory, inconclusive or have not determined the phenomena in detail or robustly, and I will not discuss these here.…”
