Universal non-resonant explanation to charmoniumlike structures $Z_c(3885)$ and $Z_c(4025)$

Abstract

Different from the usual tetraquark assignment to charged $Z_c(3885)$ and $Z_c(4025)$ charmoniumlike structures, in this letter we propose a universal non-resonant explanation to decode these $Z_c$'s, which is based on a special dynamical behavior of $e^{+}{e}^{-}\to D^{(\ast )}{\bar{D}}^{\ast }\pi$. Our study shows that $Z_c(3885)$ and $Z_c(4025)$ are only the reflection from the $P$-wave charmed meson $D_1(2420)$ involved in $e^{+}{e}^{-}\to D^{(\ast )}{\bar{D}}^{\ast }\pi$. Obviously, the present work provides a unique perspective, which can be examined by future experiments like BESIII and BelleII.
