The operation of masses carried out by the doubly heavy triquark-diquark model, whose results suggests the existence of stable states $cc\\bar s ud$ with the parity $J^P=\\frac{1}{2}^-$. The roughly calculation about lifetimes show the short magnitudes, $(4.65^{+0.71}_{-0.55})\\times 10^{-13}s $ for the parity $J^P=\\frac{1}{2}^-$ and $(0.93^{+0.14}_{-0.11})\\times 10^{-12} s $ for $J^P=\\frac{3}{2}^-$.
