Analytical dispersive parameterization for S-wave $\pi \pi$ and $\pi K$ scattering

Volodymyr Biloshytskyi, Igor Danilkin, Xiu-Lei Ren +1

In this proceeding, we illustrate the applicability of a new parameterization of the S-wave amplitude on the example of the $\pi \pi \to \pi \pi$ and $\pi K\to \pi K$ lattice data ($m_{\pi }\sim 240$…
