Low-energy Scattering of $(D{\bar{D}}^{\ast }{)}^{\pm }$ System And the Resonance-like Structure $Z_c(3900)$

Ying Chen, Ming Gong, Yu-Hong Lei +13

In this exploratory lattice study, low-energy scattering of the $(D{\bar{D}}^{\ast }{)}^{\pm }$ meson system is analyzed using lattice QCD with $N_f=2$ twisted mass fermion configurations wit…
