The $DD^*$ scattering phase shifts in the $T_{cc}^+ = cc\bar{u}\bar{d}$ channel are extracted from lattice QCD for five different charm quark masses and a fixed light-quark mass corresponding to $m_{\pi} \simeq$ 280  MeV. The phase shifts are analyzed employing two approaches: effective range expans ...

Experimentally, the doubly charm tetraquark channel $cc\bar{q}\bar{q}$ with $q=u$, $d$ features an exotic hadron, $T_{cc}$, with isospin $I=0$ near the $DD^*$ threshold, while no peak was observed for $I=1$. We present a lattice QCD study of this channel with $I=1$, $J^P=1^+$,and $m_{\pi} \simeq 280 ...

Many exotic charmoniumlike mesons have already been discovered experimentally, of which the $Z_c$ mesons with isospin 1 are prominent examples. We investigate $J^{PC}=1^{+\pm}$ states with flavor $\bar{c}c\bar{q}q (q=u,d)$ in isospin 1 using lattice QCD. This is the first study of these mesons emplo ...
