英文摘要	Starting from the hypothesis that the T thorn ccdiscovered at LHCb is a D ⠂ thorn D0=D ⠂0D thorn hadronic molecule, we consider the partial width of its heavy quark spin partner, the Tcc ⠂ thorn as a D ⠂ thorn D ⠂0shallow bound state, decaying into the D ⠂D pi final states including the contributions of the D ⠂D and D ⠂pi final state interaction by using a nonrelativistic effective field theory. Because of the existence of the T thorn ccpole, the I1/40D ⠂D rescattering can give a sizeable correction up to about 40% to the decay widths considering only the tree diagrams, and the D ⠂pi rescattering correction is about 10%. The four-body partial widths of the T ⠂ thorn cc into DD pi pi are also explicitly calculated, and we find that the interference effect between different intermediate D ⠂D pi states is small. The total width of the T ⠂ thorn cc is predicted to be about 41 keV.
