The mass of the $J^P=1/2^+$ $\\Xi_{cc}$ ground state is predicted to be 3606 MeV, which is consistent with the mass of $\\Xi_{cc}^{++}(3621)$ newly observed by the LHCb collaboration. The predicted mass gap between two $S$ wave states, $\\Xi_{cc}^*$ ($J^P=3/2^+$) and $\\Xi_{cc}$ ($J^P=1/2^+$), is 69 MeV. Furthermore, the radiative transitions of doubly heavy baryons are also estimated by using the realistic wave functions obtained from relativized quark model.
