In the present work, we propose $Y(4140)$ as the $\chi_{c1}(3P)$ state by studying the $\chi_{c1} \pi^+ \pi^-$ invariant mass spectrum of the $B\to K \chi_{c1} \pi^+ \pi^-$ process. In the $D\bar{D}$ invariant mass spectrum of the $B\to K…

The three body decays $B \to D^{(*)} \bar{D}^{(*)} K_s$ may be used to measure both $\sin{2\beta}$ and $\cos{2\beta}$. Crucial to the $\cos{2\beta}$ measurement is the resonant contribution to the three body decay from p-wave excited $D_s$…

We conduct a theoretical study of the $ D_{s1}(2460) \to D_s \pi^+ \pi^- $ decay from the perspective that the $D_{s1}$ is a molecular state, built mostly from the $D^* K$ and $D_s^* \eta$ components. The $D^*$ and $D_s^*$ mesons are…

We propose that the broad $1^{--}$ resonance structure recently discovered by BES in $J/\psi\to K^{+}K^{-}\pi^{0}$ is the P-wave excitation of a diquark-antidiquark bound state. This interpretation implies that there exists a negative…

We study the excited states of $\omega$ and $\omega_3$ by comparison with the $\rho$ and $\rho_3$ families, and discuss the possibility of $X(2220)$ as $\omega$ excitation by analyzing the mass spectra and strong decay behaviors. In…
