Reactions $K^{-}p\to {\Sigma }^{-}{\pi }^{+}$ and $K^{-}p\to {\Sigma }^{+}{\pi }^{-}$ in the momentum range from 220 to 470 MeV/c

We present the analysis of 64 000 $K^{-}p\to {\Sigma }^{-}{\pi }^{+}$ and 89 000 $K^{-}p\to {\Sigma }^{+}{\pi }^{-}$ events obtained with the Berkeley 25-in. hydrogen bubble chamber. Total cross sections and Legendre-polynomial expansion coefficients describing the differential cross sections and polarizations are presented in 10-MeV/c momentum intervals extending from 220 to 470 MeV/c. This paper completes the series devoted to all $K^{-}p$ final states in this momentum range.
