Description
We have performed calculations for the states $\Omega_{cc}$, $\Omega_{bc}$ and $\Omega_{bb}$ stemming from coupled channel interactions between the pseudoscalar or vector mesons and the $1/2^+$, $3/2^+$ baryons. In all cases, we find bound states or resonances, using the Bethe-Salpeter equation to unitarize the interaction of the coupled channels with the input for the potential obtained from an expression of the local hidden gauge approach to the charm and beauty sectors. These states are presently under investigation by the LHCb Collaboration.
