Interpretation of Y(4390) as an isoscalar partner of Z(4430) from \({D^{*}}(2010){\bar{D}}_1(2420)\) interaction

Invoked by the recent observation of Y(4390) at BESIII, which is about 40 MeV below the \({D^{*}}(2010){\bar{D}}_1(2420)\) threshold, we investigate possible bound and resonance states from the \({D^{*}}(2010){\bar{D}}_1(2420)\) interaction with the one-boson-exchange model in a quasipotential Bethe–Salpeter equation approach. A bound state with quantum number \(0^-(1^{-\,-})\) is ...

Exploring the \(\Upsilon (6S)\rightarrow \chi _{bJ}\phi \) and \(\Upsilon (6S)\rightarrow \chi _{bJ}\omega \) hidden-bottom hadronic transitions

In this work, we investigate the hadronic loop contributions to the \(\Upsilon (6S) \rightarrow \chi _{bJ} \phi ~(J=0,1,2)\) along with \(\Upsilon (6S) \rightarrow \chi _{bJ} \omega ~(J=0,1,2)\) transitions. We predict that the branching ratios of \(\Upsilon (6S) \rightarrow \chi _{b0} \phi \), \(\Upsilon (6S) \rightarrow \chi _{b1} \phi \) and \(\Upsilon (6S) \rightarrow \chi ...

Hidden-charm decays of X(3915) and Z(3930) as the P-wave charmonia

In this work, we investigate the $X(3915)$ and $Z(3930)$ decays into $J/\psi \omega$ with the $\chi _{c0}^\prime (2P)$ and $\chi _{c2}^\prime (2P)$ assignments to $X(3915)$ and $Z(3930)$, respectively. The results show that the decay width of $Z(3930)\to J/\psi \omega$ is at least one order smaller than that of $X(3915)\to J/\psi \omega$. This observation explains why only one ...

\(D_{s1}^*(2860)\) and \(D_{s3}^*(2860)\) : candidates for \(1D\) charmed-strange mesons

Newly observed two charmed-strange resonances, \(D_{s1}^*(2860)\) and \(D_{s3}^*(2860)\) , are investigated by calculating their Okubo–Zweig–Iizuka-allowed strong decays, which shows that they are suitable candidates for the \(1^3D_1\) and \(1^3D_3\) states in the charmed-strange meson family. Our study also predicts other main decay modes of \(D_{s1}^*(2860)\) and ...

Prediction of a missing higher charmonium around 4.26 GeV in \(J/\psi \) family

Inspired by the similarity between the mass gaps of the \(J/\psi \) and \(\Upsilon \) families, the prediction of a missing higher charmonium with mass 4,263 MeV and very narrow width is made. In addition, the properties of two charmonium-like states, \(X(3940)\) and \(X(4160)\), and charmonium \(\psi (4415)\) are discussed, where our calculation shows that \(X(3940)\) as \(\eta ...

Simulating the charged charmoniumlike structure \(Z_c(4025)\)

Inspired by the recent observation of the charged charmoniumlike structure \(Z_c(4025)\), we explore the \(Y(4260)\rightarrow (D^*\bar{D}^*)^- \pi ^+\) decay through the initial-single-pion-emission mechanism, where the \(D^*\bar{D}^*\rightarrow D^*\bar{D}^*\) interaction is studied by the ladder approximation, including the non-interacting case. Our calculation of the differential ...
