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

Paolo M. Gensini, Rafael Hurtado, Galileo Violini

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…
