“…Alternatively, the new structure reported by the Belle collaboration [15] is considered as a 𝐷 * D* molecule with 𝐽 PC = 0 ++ . [37,38] However, in this case, one would expect a strong 𝑆-wave coupling to the 𝐷 D channel for such a state and, therefore, naturally a large total width, contrary to what is observed at Belle. The compact tetraquark model [39][40][41][42] and the conventional 2𝑃 charmonium picture [43,44] have been employed to explore the 2 ++ states, even though the authors of those works were not primarily focused on the 𝑋2 state.…”

In 2021, the Belle Collaboration reported the first observation of a new structure in the $\psi(2S) \gamma$ final state produced in the two-photon fusion process. In the hadronic molecule picture, this new structure can be associated with the shallow isoscalar $D^*\bar{D}^*$ bound state and as such is an excellent candidate for the spin-2 partner of the $X(3872)$ with the quantum numbers $J^{PC}=2^{++}$ conventionally named $X_2$. In this work we evaluate the electronic width of this new state and argue that its nature is sensitive to its total width, the experimental measurement currently available being unable to distinguish between different options. Our estimates demonstrate that the planned Super $\tau$-Charm Facility offers a promising opportunity to search for and study this new state in the invariant mass distributions for the final states $J/\psi\gamma$ and $\psi(2S)\gamma$.

“…The experimental and theoretical effort required makes the study of these exotic states an intriguing field in hardonic physics. These achievements and progresses provide good opportunities for us to investigate the internal structures of exotica, and recent experimental and theoretical statuses can be found in reviews [1][2][3][4][5][6][7][8][9][10].…”

We adopt the quark pair creation model to investigate the light meson emissions of several charmonium-like states. The quark pair creation model is applied to the four-body systems, and we calculate the pion/kaon emissions of the $X(4700)$, $Z_c(4430)$, $Y(4230)$, $Y(4360)$, $Y(4390)$ and $Y(4660)$ within the compact tetraquark assumptions. It is found that the pion/kaon decay widths for the $X(4700)$ and $Z_c(4430)$ are relatively small, while the partial decay widths for the resonances $Y(4230)$, $Y(4360)$, $Y(4390)$ and $Y(4660)$ are significant. We expect that our exploration of these decay behaviors can provide useful information for future experimental searches and theoretical interpretations.

“…The X(3940), X(4020) and X(4050) states have been identified as hidden-charm tetraquarks with dominant diquark-antidiquark components in a quark model framework [76]. The X(4014) has been assigned as a D * D * molecule with J P C = 0 ++ [77,78]. Three more hidden-charm states, ψ(4230), ψ(4360) and ψ(4415), have been predicted to be J P C = 0 −− D ( * ) D( * ) molecular bound-states within an effective field theory approach [79].…”
