Discovery of the doubly charmed Tcc+ state implies a triply charmed Hccc hexaquark state

Tian-Wei Wu et al.

Summary: The paper investigates the recently discovered doubly charmed exotic state T-cc and suggests that it could be a molecular state predicted in theoretical models. The study presents a potential DDD* state and its main decay modes.

Is Z(cs)(3982) a molecular partner of Z(c)(3900) and Z(c)(4020) states?

V Baru et al.

Summary: An effective field theory-based coupled-channel analysis of e(+)e(-) annihilation data at BES III was performed, extracting poles responsible for the Z(cs)(3982) formation. Two scenarios were identified, providing similar mass distribution descriptions but differing predictions for the spin partners of Z(cs)(3982).

A phenomenological analysis on isospin-violating decay of X(3872)

Qi Wu et al.

Summary: In a molecular scenario, the study on the isospin-breaking hidden charm decay processes of X(3872) reveals that the different coupling strengths of X(3872) contribute to the isospin violation, resulting in consistent experimental measurements within the determined parameter range. Further precise measurements are needed to test the estimated partial width ratio of pi 0 chi cJ for J=0,1,2.

Is X(7200) the heavy anti-quark diquark symmetry partner of X(3872)?

Ming-Zhu Liu et al.

Summary: This study investigates the possible existence of molecules in systems such as D()Xi cc(), Xi cc()Xi cc(), B()B(), B()Xi bb(), and Xi bb()Xi bb() using heavy anti-quark di-quark symmetry. Through the analysis, various molecular states are predicted in different systems, with the implication that X(7200) may be related to X(3872) in some way.

Decoding the nature of Zcs(3985) and establishing the spectrum of charged heavy quarkoniumlike states in chiral effective field theory

Bo Wang et al.

Summary: In this study, the charmoniumlike state Z(cs)(3985) is analyzed within the framework of chiral effective field theory, showing consistent mass, width, and event distributions with experimental measurements. The interaction of the (D) over bar (s) D*/ (D) over bar (s)* D system is calculated up to next-to-leading order, supporting the Z(cs)(3985) as a molecular resonance with the same origin as other charged heavy quarkonium-like states. Precise predictions for the parameters of unobserved states in various systems are made, establishing a complete spectrum of charged charmoniumlike and bottomoniumlike states with specific quantum numbers.
