$T_{cc}^{+}(3875)$ relevant $D{D}^{\ast }$ scattering from $N_f=2$ lattice QCD

Siyang Chen, Chunjiang Shi, Ying Chen +4

The $S$-wave $D{D}^{\ast }$ scattering in the isospin $I=0,1$ channels is studied in $N_f=2$ lattice QCD at $m_{\pi }\approx 350$ MeV. It is observed that the $D{D}^{\ast }$ interaction is repulsive in…
