abstract
Using the vector-exchange interaction in the local hidden gauge approach, which in the light quark sector generates the chiral Lagrangian, and has produced realistic results for $\Omega_c, \Xi_c, \Xi_b$ and the hidden charm pentaquark states, we study the meson-baryon interactions in the coupled channels that lead to the $\Xi_{bb}$ and $\Omega_{bbb}$ excited states of the molecular type. We obtain seven states of the $\Xi_{bb}$ type with energies between $10408$ and $10869$ MeV and one $\Omega_{bbb}$ state at $15212$ MeV.

Prediction of $QQqq\bar{s}$ molecular pentaquarks within the extended local hidden gauge approach
A model calculation predicts fourteen double-heavy molecular pentaquark states, but their existence and binding energies depend critically on an unconstrained regularization parameter.

Determination of the binding and $DK$ probability of the $D^{*}_{s0}(2317)$ from the $(\bar{D}\bar K)^-$ mass distributions in $\Lambda_{b}\to \Lambda_{c} (\bar{D}\bar K)^-$ decays
A simulation-based feasibility study shows that near-threshold Dbar Kbar mass distributions from Lambda_b decays could determine the D*_s0(2317) mass to about 4 MeV and its DK molecular probability to about 11%.
