Strange baryons with two heavy quarks

Abstract

The LHCb Experiment at CERN has observed a doubly-charmed baryon ${\Xi }_{cc}^{++}=ccu$ with a mass of $3621.40\pm 0.78$ MeV, consistent with many predictions. We use the same methods that led us to predict $M({\Xi }_{cc},J^P=1/2^{+})=3627\pm 12$ MeV and $M({\Xi }_{cc}^{\ast },J^P=3/2^{+})=3690\pm 12$ MeV to predict $M({\Omega }_{cc}^{+},J^P=1/2^{+})=3692\pm 16$ MeV and $M({\Omega }_{cc}^{\ast },J^P=3/2^{+})=3756\pm 16$ MeV. Production and decay are discussed briefly, and predictions for $M({\Omega }_{bc})$ and $M({\Omega }_{bb})$ are included.
