Description
A study of the charmless baryonic decays $B^0_{(s)} \to K^0 p \bar{p}$ is reported using $9~\mathrm{fb}^{-1}$ of LHCb data at 7, 8, and 13 TeV. The decay $B^0_s \to K^0 p \bar{p}$ is observed for the first time with a branching fraction of $(9.14 \pm 1.69 \pm 0.90 \pm 0.33 \pm 0.20)\times 10^{-7}$ and a significance of $5.6\sigma$. For $B^0 \to K^0 p \bar{p}$, the branching fraction is measured as $(2.82 \pm 0.08 \pm 0.12 \pm 0.10)\times 10^{-6}$, representing the most precise determination to date.
