Coupled-channel description of charmed heavy hadronic molecules within the meson-exchange model and its implication

Lin Qiu, Chang Gong, Qiang Zhao

Motivated by the first observation of the double-charm tetraquark $T_{cc}^{+}(3875)$ by the LHCb Collaboration, we investigate the nature of $T_{cc}^{+}$ as an isoscalar $D{D}^{\ast }$ hadroni…
