Role of $\Xi (1690)$ in the $J/\psi \to {\Xi }^0\bar{\Lambda }{K}^0$ reaction

Wen-Tao Lyu, Lian-Rong Dai, Eulogio Oset

Motivated by the recent BESIII measurements of the $J/\psi \to {\Xi }^0\bar{\Lambda }{K}_S^0+c.c.$ process, we investigate this reaction by considering the contributions from the $\Xi (1690)$, $Λ(1890…
