Hidden charm ${\mathcal{P}}_{cs}(4338{)}^0$ production in baryonic $B^{-}\to J/\psi \Lambda \bar{p}$ decay

Yu-Kuo Hsiao, Shu-Ting Cai, Yan-Li Wang

We investigate the resonant baryonic $B$ decay $B^{-}\to {\mathcal{P}}_{cs}^0\bar{p},{\mathcal{P}}_{cs}^0\to J/\psi \Lambda$, where ${\mathcal{P}}_{cs}^0\equiv {\mathcal{P}}_{cs}(4338{)}^0$ is identified as a hidden…
