In 2019, two new structures $\Lambda_b(6146)$ and $\Lambda_b(6152)$ were observed by the LHCb Collaboration at the invariant mass spectrum of $\Lambda_b^0\pi^{+}\pi^{-}$, which aroused a hot discussion about their inner structures. The…

The baryon-antibaryon spectrum consisting of strange, charm and bottom quarks is studied in the color flux-tube model with a multi-body confinement interaction. Numerical results indicate that many low-spin baryon-antibaryon states can form…
Recently, a hint for dibaryon $N\Delta(D_{21})$ was observed at WASA-AT-COSY with a mass about $30\pm10$ MeV below the $N\Delta$ threshold. It has a relatively small binding energy compared with the $d^*(2380)$ and a width close to the…

Currently, there is much controversy surrounding the interpretation of the $\Xi(2030)$ and $\Xi(2012)$ as traditional hadrons containing double strange quarks. In particular, the ratios of the partial decay widths into $\Lambda\bar{K}$ and…
The octet meson and baryon interaction with strangeness $S=-1$ is studied fully relativistically with chiral Lagrangian. In this work, a Bethe-Salpeter equation approach with spectator quasipotential approximation is applied to study the…

The developments in the experimental facilities and analyses techniques have recently lead to the observation of many hadronic states ranging from excitations of conventional hadrons to various exotic states. The baryons with single heavy…

We have studied the meson-baryon interaction in coupled channels with the same quantum numbers of $\Xi_{bc}$. The interaction is attractive in some channels and of sufficient intensity to lead to bound states or resonances. We use a model…
