A coupled-channel lattice study on the resonance-like structure $Z_c(3900)$

Ting Chen, Ying Chen, Ming Gong +7

In this exploratory study, near-threshold scattering of $D$ and ${\bar{D}}^{\ast }$ meson is investigated using lattice QCD with $N_f=2+1+1$ twisted mass fermion configurations. The calcul…
