Descripción
In this talk, a dispersive approach is presented to extract the s-wave $\eta\pi$ scattering phase shift in the elastic regime from BESIII $\eta^{\prime} \rightarrow \eta \pi \pi $ experimental data. This approach relies on unitarity and the structure of two-body partial wave amplitudes with an analytical closed formula for the Right-Hand-Cut and a conformal mapping for the Left-Hand-Cut. Finally, three-body final state interactions are modeled with the Khuri-Treiman equations
