论文摘要
在本说明中，我们首先介绍了在无限和有限体积中两体散射的统一性的理论形式主义。然后，我们将这种形式主义应用于$ j/ψ\，π$和$ d \ bar {d}^{*} $ coupled-channel散射中的$ z_c（3900）$共振的研究。最近的晶格有限体积光谱与我们的预测相遇。
In this note we first introduce the theoretical formalism of the unitarization of the two-body scattering both in the infinite and finite volumes. Then we apply this formalism to the study of the $Z_c(3900)$ resonance in the $J/ψ\,π$ and $D\bar{D}^{*}$ coupled-channel scattering. The recent lattice finite-volume spectra are confronted with our predictions.
