Strangeness is the key: from $K ˉ N$ to $D ˉ_{s} D K$

Li-Sheng Geng, Ming-Zhu liu, Jia-Ming Xie

The kaon, the lightest hadron containing a strangeness quark, is very peculiar. It is a Nambu-Goldstone boson, but significantly heavier than the pion. As a result, its interaction…

Probing the three-body force in hadronic systems with specific charge parity

Ya-Wen Pan, Ming-Zhu Liu, Li-Sheng Geng

Three-body forces, a type of non-perturbative strong interaction, are widely studied in nuclear physics. However, whether their inclusion is necessary in nuclear systems remains a…

Implication of a negative effective range on the $D D ˉ^{*}$ interaction and the nature of $X (3872)$

Yi-Bo Shen, Ming-Zhu Liu, Zhi-Wei Liu +1

A recent analysis of the LHCb data [Phys. Rev. D 105 (2022) L031503] obtained a sizable negative effective range for the $X (3872)$ . This has attracted intensive discussions on whet…

Studying the heavy quark spin symmetry multiplet of hadronic molecules $D ˉ^{()} Σ_{c}^{()}$ in the three-body decays of $D ˉ^{(*)} Λ_{c} π$

Ming-Zhu Liu, Ya-Wen Pan, Li-Sheng Geng

The decay behavior of an exotic state can be used to probe its internal structure. We note that the hidden-charm pentaquark states, $P_{ψ}^{N} (4312)$ , $P_{ψ}^{N} (4440)$ , and $P_ψ^{N}(4…

Investigations on the weak decays of $D B ˉ$ molecules

Ming-Zhu Liu, Li-Sheng Geng

The decays of exotic states discovered experimentally always proceed via the strong and electromagnetic interactions. Recently, a tetraquark state with the quark content $bc\bar{q}…

Femtoscopy can tell whether $Z_{c} (3900)$ and $Z_{cs} (3985)$ are resonances or virtual states

Zhi-Wei Liu, Jun-Xu Lu, Ming-Zhu Liu +1

There have been extended and heated discussions on the nature of the two exotic states, $Z_{c} (3900)$ and $Z_{cs} (3985)$ , particularly whether they are near-threshold resonances, vir…

Ming-Zhu Liu, Xi-Zhe Ling, Li-Sheng Geng

The two excited vector charmonium states $Y (4220)$ and $Y (4360)$ are difficult to be understood as pure $c c ˉ$ charmonium states. Since they are located close to the mass thres…

Three ways to decipher the nature of exotic hadrons: multiplets, three-body hadronic molecules, and correlation functions

Ming-Zhu Liu, Ya-Wen Pan, Zhi-Wei Liu +3

In the past two decades, a plethora of hadronic states beyond the conventional quark model of $q q ˉ$ mesons and $q q q$ baryons have been observed experimentally, which motivated…

Systematic studies of $D D K K$ and $D D ˉ K K ˉ$ four-hadron molecules

Ya-Wen Pan, Ming-Zhu Liu, Jun-Xu Lu +1

Assuming that $D_{s 0}^{*} (2317)$ is a $D K$ molecular state with a binding energy of 45 MeV, we investigate the existence of four-hadron molecules, $D D K K$ and $D\Bar{D}K\Bar{K}$, wi…
