“…The experiment did not confirm or contradict the existence of the two-peak hypothesis. The result inspired various theoretical works [401,324,402,357,403,404,405,406,407,408]. Most of them favored the P cs as the Ξ c D * molecule [403,401,404,405,406,407,408,409].…”

“…These features inspired the interpretations of the Z cs (3985) as the SU(3) partner of the Z c (3900) [297,298,299]. The discovery of the Z cs (3985) has stimulated many works to explain its nature from various aspects [297,298,299,300,301,302,303,304,305,306,307,308,309,310,311,312,313,314,315,316,317,260,318,319,320,321,322,323,324,325,326,327,328]. Later, the LHCb Collaboration reported two Z cs states-the Z cs (4000) and Z cs (4220) in the J/ψK + channel from the process B + → J/ψK + φ [329].…”

“…Most of them favored the P cs as the Ξ c D * molecule [403,401,404,405,406,407,408,409]. Besides the molecular interpretation, there also exist other explanations such as the hadro-charmonium [324], compact pentaquark states [402,357]. There were intensive discussions of its production, decays and other properties [410,411,412].…”

Chiral symmetry and its spontaneous breaking play an important role both in the light hadron and heavy hadron systems. In this work, we shall review the investigations on the chiral corrections to the properties of the heavy mesons and baryons within the framework of the chiral perturbation theory (χPT). We will also review the scatterings of the light pseudoscalar mesons and heavy hadrons. Moreover, the modern nuclear force was built upon the chiral effective field theory (χEFT). In the past decades many new hadron states were observed experimentally. A large group of these states are near-threshold resonances, such as the charged charmoniumlike Z c and Z cs states, bottomoniumlike Z b states, hidden-charm pentaquark P c and P cs states and the doubly charmed T cc state etc. They are very good candidates of the loosely bound molecular states composed of a pair of charmed hadrons. The same chiral dynamics not only governs the nuclei and forms the deuteron, but also dictates the above shallow bound states or resonances. We will perform an extensive review on the progress on the heavy hadronic molecular states within the framework of χEFT.

The past decades witnessed the golden era of hadron physics. Many excited open heavy flavor mesons and baryons have been observed since 2017. We shall provide an updated review of the recent experimental and theoretical progresses in this active field. Besides the conventional heavy hadrons, we shall also review the recently observed open heavy flavor tetraquark states X(2900) and T + cc (3875) as well as the hidden heavy flavor multiquark states X(6900), P cs (4459) 0 , Z cs (3985) − , Z cs (4000) + , and Z cs (4220) + . We will also cover the recent progresses on the glueballs and light hybrid mesons, which are the direct manifestations of the non-Abelian SU (3) gauge interaction of the Quantum Chromodynamics in the low-energy region.

This work presents an analysis of a hidden charmed pentaquark candidate state with double strange quark in its quark content. The investigation is performed in two parts, which provide the mass prediction of the considered state and its partial decay width for the Pcss → Ξ 0 J/ψ channel. For the analyses, two-point and three-point QCD sum rule methods are applied to get the mass and the width, respectively. The mass for this candidate state is obtained as mP css = 4600 ± 155 MeV with corresponding current coupling constant λP css = (0.81 ± 0.21) × 10 −3 GeV 6 . These results are used in the analysis of the partial width of this state for the decay Pcss → Ξ 0 J/ψ. For this decay, the width is obtained as Γ = 9.52 ± 2.85 MeV. These results may shed light on the future experimental searches in which such types of states are probed and may provide information to discriminate between such possible observations.
