Abstract Inspired by the newly observed $$\Omega _b$$ Ωb states by the LHCb Collaboration, we investigate the two-body strong decays of the low-lying $$\lambda $$ λ -mode $$\Omega _b$$ Ωb baryons up to $$N=2$$ N=2 shell using the chiral quark mode

Abstract Inspired by the new resonance Y(10750), we calculate the masses and two-body OZI-allowed strong decays of the higher vector bottomonium sates within both screened and linear potential models. We discuss the possibilities of $$\Upsilon (10860

We show that the Pomeron exchanges play a unique role in vector charmonium scatterings. Such a mechanism can provide a natural explanation for the nontrivial structures in the di-J/ψ spectrum observed by the LHCb Collaboration. The narrow structure

Abstract We calculate the $$\Lambda _c{\bar{\Lambda }}_c$$ ΛcΛ¯c partial decay width of the excited vector charmonium states around 4.6 GeV with the quark pair creation model. We find that the partial decay width of the $$\Lambda _c{\bar{\Lambda }

Abstract Considering the mass, parity and $$D^0 p$$ D0p decay mode, we tentatively assign the $$\Lambda _c(2940)$$ Λc(2940) as the $$P-$$ P- wave states with one radial excitation. Then, via studying the strong decay behavior of the $$\Lambda _c(294

A semi-relativistic potential model is adopted to calculate the mass spectra of charmed and charmed-strange meson states up to the $2D$ excitations.The strong decay properties are further analyzed with a chiral quark model by using the numerical wave
