The $K^{-}p\to \eta \Lambda$ reaction in an effective Lagrangian model

Bo-Chao Liu, Ju-Jun Xie

We report on a theoretical study of the $K^{-}p\to \eta \Lambda$ reaction near threshold by using an effective Lagrangian approach. The role of $s-$channel $\Lambda (1670)$, $t-$channel $K^{\ast }$ and $…
