Study on the structure of the $Z_{c} (3900)$ state

Yan Ma, De-Shun Zhang, Cheng-Qun Pang +1

In this work, we studied the $Z_{c} (3900)$ state within the framework of effective field theory. We firstly show the construction of the Lagrangian describing meson-meson-meson and…

Can the three new states around 2.2 GeV assign to $ω (3 D)$

Ya-rong Wang, Yang Ma, Cheng-qun Pang

Recently, the BESIII Collaboration reported three resonances: $X (2232)$ with $M = 2232 \pm 19 \pm 27$ MeV and $Γ = 93 \pm 53 \pm 20$ MeV, $X (2200)$ whose mass $M = 2200 \pm 11 \pm 1…
