Precision Low-Energy Measurements at DA$\Phi$NE and Their Impact on $\bar{K}N$ Physics

Abstract

We delineate a ``theoretical'' $\chi^2$--functional technique to implement fixed--$t$ analyticity on the invariant amplitudes for the $\bar{K}N$, $\pi\Lambda$, $\pi\Sigma$ coupled channels in a fast and straightforward way.
