The $K^{-}{\pi }^{+}$ S-wave from the $D^{+}\to K^{-}{\pi }^{+}{\pi }^{+}$ decay

The FOCUS Collaboration

Using data from FOCUS (E831) experiment at Fermilab, we present a model independent partial-wave analysis of the $K^{-}{\pi }^{+}$ S-wave amplitude from the decay $D^{+}\to K^{-}{\pi }^{+}{\pi }^{+}$. The S…
