On the generalized Friedrichs-Lee model with multiple discrete and continuous states

Zhiguang Xiao, Zhi-Yong Zhou

In this study, we present several improvements of the non-relativistic Friedrichs-Lee model with multiple discrete and continuous states and still retain its solvability. Our findi…

Reconciling experimental and lattice data of $Z_{c} (3900)$ in a $J / ψ π$ - $D D ˉ^{*}$ coupled-channel analysis

Lin-Wan Yan, Zhi-Hui Guo, Feng-Kun Guo +2

We study the $J / ψ π$ and $D D ˉ^{*}$ coupled-channel system within a covariant framework. The $J / ψ π$ and $D D ˉ^{*}$ invariant-mass distributions measured at 4.23~GeV and 4.26~GeV…

A new look at $ψ (4160)$ and $ψ (4230)$

Zhi-Yong Zhou, Chun-Yong Li, Zhiguang Xiao

By simultaneously analyzing the cross section data of $e^{+} e^{-} \to D D ˉ, D D ˉ^{*}, D^{*} D ˉ^{*}, D D ˉ π$ in a coupled-channel scheme with unitarity, we found that, in co…
