A chiral quark model study of $Z^{+}(4430)$ in the molecular picture

Yan-Rui Liu, Zong-Ye Zhang

We investigated the bound state problem of the S wave charged $D_1{\bar{D}}^{\ast }$ ($D_1^{\prime }{\bar{D}}^{\ast }$) system in a chiral quark model by solving the resonating group method equation. Our…
