“…The currently available LQCD calculations that are relevant to the Z c (3900) suffer from a number of uncertainties, as has been recently reviewed in Ref. [73]. These include the lattice spacing, the volume, the physical π mass, and the channels that are considered in the calculation.…”

Charmonium is a bound state of a charmed quark and a charmed antiquark, and a charmoniumlike state is a resonant structure that contains a charmed quark and antiquark pair but has properties that are incompatible with a conventional charmonium state. While operating at center-of-mass energies from 2 to 4.9 GeV, the BESIII experiment can access a wide mass range of charmonium and charmoniumlike states, and has contributed significantly in this field. We review BESIII results involving conventional charmonium states, including the first observation of M1 transition ψ(2S) → γη c (2S) and the discovery of the ψ 2 (3823); and report on studies of charmoniumlike states, including the discoveries of the Z c (3900) and Z c (4020) tetraquark candidates, the resolution of the fine structure of the Y (4260), the discovery of the new production process e + e − → γX(3872), and the uncovering of strong evidence for the commonality among the X(3872), Y (4260), and Z c (3900) states. The prospects for further research at BESIII and proposed future facilities are also presented.

“…Subsequently, there is a lot of theoretical work to study Z c (3900) and its associated states. Some researches treated it as the tightly bound diquark-antidiquark state [5][6][7][8][9][10]. However, many researches treated it as molecular states [11][12][13][14][15][16][17].…”

Strange hidden-charm tetraquarks in constituent quark models

Inspired by the newly reported Zcs(3985) − by the BESIII Collaboration, we systematically investigate the strange hidden-charm tetraquark systems cscū with two structures: meson-meson and diquark-antidiquark. Two quark models: the chiral quark model (ChQM) and the quark delocalization color screening model (QDCSM) are used here. Similar results are obtained in both two quark models. There is no any bound state in either ChQM or QDCSM, which excludes the molecular state explanation (DsD * /D * s D/D * s D * ) of the reported Zcs(3985) − . However, the effective potentials for the diquark-antidiquark cscū systems shows the possibility of some resonance states with mass range of 3916.5 ∼ 3964.6 MeV for IJ P = 1 2 0 + , 4008.8 ∼ 4091.2 MeV for IJ P = 1 2 1 + , 4246.8 ∼ 4418.1 MeV for IJ P = 1 2 2 + . So the observed Zcs(3985) − state is possible to be explained as a compact resonance state composed of cscū with IJ P = 1 2 0 + or IJ P = 1 2 1 + . The study of the scattering process of corresponding open channels is under way to check this conclusion.

“…Another important development was the proposal 2 for a complete renormalization scheme [36,47], which was complemented by the proof of renormalizability of non-local operators to all orders in perturbation theory [48][49][50][51][52][53]. Last but not least, a well-defined matching prescription appropriate for the various renormalization schemes has been developed [54][55][56][57][58][59]. All this progress and the ability to calculate PDFs at the physical point led to the need to refine the lattice estimates, with in-depth studies of various sources of systematic uncertainties.…”

The x-dependence of hadronic parton distributions: A review on the progress of lattice QCD

In this article, we review recent lattice calculations on the x-dependence of parton distributions, with the latter providing information on hadron structure. These calculations are based on matrix elements of boosted hadrons coupled to non-local operators and can be related to the standard, light-cone distribution functions via an appropriate factorization formalism. There is significant progress in several directions, including calculations of flavor-singlet parton distribution functions (PDFs), first calculations of generalized parton distributions (GPDs), as well as the implementation of some of the approaches for the transverse-momentumdependent PDFs (TMD PDFs). This new direction of lattice calculations is particularly interesting for phenomenological fits on experimental data sets, as the lattice results can help improve the constraints on the distribution functions.
