$\Sigma$ Resonances from $K^{-}N\to \pi \Lambda$ reactions with the center of mass energy from 1550 to 1676 MeV

Puze Gao, Jun Shi, B. S. Zou

For the study of the $\Sigma$ resonances, we analyze the differential cross sections and $\Lambda$ polarizations for the reactions $K^{-}n\to {\pi }^{-}\Lambda$ and $K^{-}p\to {\pi }^0\Lambda$ with an effective Lagrangian…
