$\Xi (1690{)}^{-}$ production in the $K^{-}p\to K^{+}{K}^{-}\Lambda$ reaction process near threshold

Jung Keun Ahn, Seung-il Nam

We investigate $\Xi (1690{)}^{-}$ production from the $K^{-}p\to K^{+}{K}^{-}\Lambda$ reaction within the effective Lagrangian approach at the tree-level Born approximation. We consider the $s$- and $u…
