“…The similar decay suppressions are also noticed with other approaches [33,[55][56][57][58][59][60][61][62][63][64][65][66][67][68]. However, we need to point out that the decays of the molecular states cannot always be predicted very reliably and are still deserved to study furthermore in future.…”

Very recently, the LHCb Collaboration at the Large Hadron Collider at CERN observed new resonance X(4630). The X(4630) is decoded as a charmoniumlike molecule with hidden-strange quantum number well in the one-boson-exchange mechanism. Especially, the study of its hidden-charmed decays explicitly shows the dominant role of $$J/\psi \phi $$ J / ψ ϕ among all allowed hidden-charmed decays of the X(4630), which enforces the conclusion of X(4630) as a charmoniumlike molecule. The discovery of the X(4630) is a crucial step of constructing charmoniumlike molecule zoo.

“…II, the hadronic molecule is a loosely bound state [51], so the binding energies of these hidden-charm molecular pentaquarks with triple strangeness change from −20 to −1 MeV in calculating the decay widths. With increasing the absolute values of the binding energy, the decay widths become larger, which is consistent with other theoretical calculations [51,[75][76][77][78][79][80][81][82][83][84][85][86]. As illustrated in Fig.…”

Motivated by the successful interpretation of these observed P c and P cs states under the meson-baryon molecular picture, we systematically investigate the possible hidden-charm molecular pentaquark states with triple strangeness which is due to the Ω ( * ) c D( * ) s interactions. We perform a dynamical calculation of the possible hiddencharm molecular pentaquarks with triple strangeness by the one-boson-exchange model, where the S -D wave mixing effect and the coupled channel effect are taken into account in our calculation. Our results suggest that the Ω c D * s state with J P = 3/2 − and the Ω * c D * s state with J P = 5/2 − can be recommended as the candidates of the hidden-charm molecular pentaquark with triple strangeness. Furthermore, we discuss the two-body hiddencharm strong decay behaviors of these possible hidden-charm molecular pentaquarks with triple strangeness by adopting the quark-interchange model. These predictions are expected to be tested at the LHCb, which can be as a potential research issue with more accumulated experimental data in near future. c D( * ) s systems with double strangeness [39] and the B ( * ) c T systems with B ( * ) c = Λ c /Σ ( * ) c and T = D1 / D * 2 [40], and predicted a series of possible candidates of the hidden-charm molecular pentaquark. At present, there is no explicit theoretical calculation with the hiddencharm molecular pentaquark states with triple strangeness. Thus, we investigate the possible hidden-charm molecular pentaquarks with triple strangeness from the Ω ( * ) c D( * ) s interactions, which will be a main task of the present work.

“…After the report of the Ω(2012) by the Belle collaboration, there were many theoretical studies on its mass, width, quantum numbers, and decay modes [392][393][394][395][396][397][398][399][400][401][402][403][404][405][406][407][408][409], which can be roughly divided into two types, the excited baryon state and the molecular state. Since the mass of the Ω(2012) state lies quite close to the threshold of the KΞ * channel with a binding energy of 15 MeV, it is quite natural to interpret Ω(2012) as a hadronic molecule composed of KΞ * .…”

According to the classification of the quark model, the hadrons going beyond three-quark baryon and quark-antiquark meson pictures are called exotic hadrons. Many new hadrons have been observed since 2003, some of which exhibit exotic behaviors. There are a lot of excellent review articles on exotic hadrons available so far; the present article tries to focus on the recent experimental and theoretical progress on the exotic states from the perspective of the quark model. Although lattice quantum chromodynamics may give the final answer of the problem, the phenomenological models are still powerful tools to explore the exotic states and to provide insight on the phenomenology of hadrons. The spatial and color structures of multiquark states and the channel coupling calculation are emphasized through reviewing some bound states, molecular and color structure resonances. Finally, the unquench effects of some exotic states are reviewed. With the accumulation of experimental data on multiquark states and inspiration of underlying theory developments, more reasonable phenomenological models incorporating multi-body interactions and high Fock components to unify the description of normal hadrons and exotic hadrons are expectable.
