Abstract: In our recent work [S. Noh and W. Park, Nonrelativistic quark model analysis of T c c , ], the mass and binding energy of T c c are found to be 3873 MeV and − 2 MeV , respectively, which align with the observations reported at LHCb [R. Aaij (LHCb Collaboration), Observation of an exotic narrow doubly charmed tetraquark, ]. Based on our latest quark model approach, we extend our search for other potentially stable configurations of doubly heavy tetraquarks using our nonrelativistic quark model described in Noh and Park, [Nonrelativistic quark model analysis of T c c , ]. Our numerical calculations indicate that the u ¯ s ¯ c b configuration is deeply bound. However, the u ¯ d ¯ c b configuration with the isospin symmetry in the light quark sector is relatively less bound. In this study, we emphasize a compulsory aspect for requiring a complete set of three-dimensional harmonic oscillator bases through the discussion of the u ¯ s ¯ c b configuration and investigate the essential differences between the u ¯ s ¯ c b and u ¯ d ¯ c b configurations.
