Measurement of branching fractions and $C\!P$ asymmetries in $\mathit{\Lambda}_b^0(\mathit{\Xi}_b^0)\!\to pK_{\mathrm S}^0h^-$ decays / LHCb Collaboration
A study of $\mathit{\Lambda}_b^0$ and $\mathit{\Xi}_b^0$ baryon decays to the final states $pK_{\mathrm S}^0\pi^-$ and $pK_{\mathrm S}^0K^-$ is performed using $pp$ collision data collected by the LHCb experiment, corresponding to an integrated luminosity of $9\,\mathrm{fb}^{-1}$. The decays $\mathit{\Lambda}_b^0\!\to pK_{\mathrm S}^0K^-$ and $\mathit{\Xi}_b^0\!\to pK_{\mathrm S}^0K^-$ are observed for the first time, with significances reaching eight standard deviations.

Improved measurement of $\eta / \eta^{\prime}$ mixing in $B^{0}_{(s)} \rightarrow J/\psi \eta^{(\prime)}$ decays / LHCb Collaboration
Branching fraction ratios between the decays $B^{0}_{(s)} \rightarrow J/\psi \eta^{(\prime)}$ are measured using proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 fb$^{-1}$. The measured ratios of these branching fractions are \[ \frac{BF(B^{0} \rightarrow J/\psi \eta^{\prime})}{BF(B^{0} \rightarrow J/\psi \eta)} = 0.48 \pm 0.06 \pm 0.02 \pm 0.01, \] \[\frac{BF(B^{0}_{s} \rightarrow J/\psi \eta^{\prime})}{BF(B^{0}_{s} \rightarrow J/\psi \eta)} = 0.80 \pm 0.02 \pm 0.02 \pm 0.01, \] where the uncertainties are statistical, systematic and related to the precision of the $\eta^{(\prime)}$ branching fractions, respectively.
