英文摘要	The isospin breaking effect plays an essential role in generating hadronic molecular states with a very tiny binding energy. Very recently, the LHCb Collaboration observed a very narrow doubly charmed tetraquark T-cc(+) in the (DD0)-D-0 pi mass spectrum, which lies just below the (DD)-D-0(+) threshold around 273 keV. In this work, we study the (DD)-D-0(+)/D+D(0) interactions with the one-boson-exchange effective potentials and consider the isospin breaking effect carefully. We not only reproduce the mass of the newly observed T-cc(+) very well in the doubly charmed molecular tetraquark scenario, but also predict the other doubly charmed partner resonance T'(+)(cc) with m = 3876 MeV, and Gamma = 412 keV. The prime decay modes of the T'(+)(cc) are (DD)-D-0+(gamma) and (D+D0)pi(0). The peculiar characteristic mass spectrum of the (DD)-D-0(+)/D+D*(0) molecular systems can be applied to identify the doubly charmed molecular states.
