The discovery of the doubly charmed tetraquark Tcc(ūd̄cc) provides a strong constraint on its binding energy compared to its lowest threshold. Using a fully convergent spatial wave function, we simultaneously fit to both the mesons and baryons. Our results indicate that a Yukawa type hyperfine potential produces to a slightly bound state for Tcc with (I,S)=(0,1), placing it below its lowest threshold, which is consistent with the experimental observations. Additionally, our study suggests that Tcc is very likely to be in a compact configuration. This original work is described in Noh and Park (2023).
