For the masses, the best predictions come from potential models and read: $M_{B_c} = (6255 \\pm 20)$~MeV, $M_{B^*_c} = (6330 \\pm 20)$~MeV, $M_{\\Lambda(bcu)} = (6.93\\pm 0.05)$~GeV, $M_{\\Omega(bcs)} = (7.00\\pm 0.05)$~GeV, $M_{\\Xi^*(ccu)} =(3.63\\pm 0.05)$~GeV and $M_{\\Xi^*(bbu)} = (10.21\\pm 0.05)$~GeV.
