The past seventeen years have witnessed tremendous progress on the experimental and
theoretical explorations of the multiquark states. The hidden-charm and hidden-bottom …

In the past decade many charmonium-like states were observed experimentally. Especially
those charged charmonium-like Z c states and bottomonium-like Z b states cannot be …

A bstract In two recent papers, we used the hadro-quarkonium model to study the properties
of hidden-charm and bottom tetraquarks and pentaquarks. Here, we extend the previous …

Very recently, the LHCb Collaboration reported a fully charmed tetraquark state X (6900) in
the invariant mass spectrum of J/ψ pairs. If one J/ψ meson is replaced with a fully charmed …

Inspired by the discovery of two pentaquarks P_ c (4380) P c (4380) and P_ c (4450) P c
(4450) at the LHCb detector, we study possible hidden-charm molecular pentaquarks in the …

We study the hadronic molecular structure of hidden heavy pentaquarks—new exotic states
composed of charmed/bottom baryons and D (D*)/B (B*) mesons. Based on the observation …

In the framework of the color-magnetic interaction, we systematically investigate the mass
spectrum of the tetraquark states composed of four heavy quarks with the QQQ¯ Q¯ …

Recently, a new hidden-charm pentaquark state P cs (4459) was reported by the LHCb
Collaboration. Stimulated by the fact that all hidden-charm pentaquark states in S= 0 …

We review how lattice QCD can contribute to the prediction and the comprehension of
tetraquarks, pentaquarks and related exotic hadrons such as hybrids, with at least one …

A bstract The LHCb collaboration have recently updated their analysis of the resonant J/𝜓 p
mass spectrum in the decay\({\varLambda} _b^ 0\)→ J/𝜓 p K−, making use of their combined …
