Low-energy Scattering of $(D^{\ast }{\bar{D}}^{\ast }{)}^{\pm }$ System and the Resonance-like Structure $Z_c(4025)$

Ying Chen, Ming Gong, Yu-Hong Lei +10

In this paper, low-energy scattering of the $(D^{\ast }{\bar{D}}^{\ast }{)}^{\pm }$ meson system is studied within Lüscher's finite-size formalism using $N_f=2$ twisted mass gauge field configu…
