Search for the production of a Higgs boson in association with a single top quark in $pp$ collisions at $\sqrt{s}~=~13$ TeV with the ATLAS detector / ATLAS Collaboration
A search for the production of a Higgs boson in association with a single top quark, $tH$, is presented. The analysis uses proton-proton collision data corresponding to an integrated luminosity of $140\mathrm{fb}^{-1}$ at a centre-of-mass energy of $13$ TeV, collected by the ATLAS detector at the LHC.

First observation of $C\!P$ violation and measurement of polarisation in $B^+ \to \rho(770)^0 K^*(892)^+$ decays / LHCb Collaboration
An amplitude analysis of the $B^+\to(\pi^+\pi^-)(K^0_{\mathrm{S}}\pi^+)$ decay is performed in the mass regions $0.30 < m_{\pi^+\pi^-} < 1.10\,\mathrm{GeV}/c^2$ and $0.75 < m_{K^0_{\mathrm{S}}\pi^+} < 1.20\,\mathrm{GeV}/c^2$, using $pp$ collision data recorded with the LHCb detector corresponding to an integrated luminosity of $9\,\mathrm{fb}^{-1}$.

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.

Precision measurement of the ${\it{\Xi}}_b^0$ baryon lifetime / LHCb Collaboration
A sample of $pp$ collision data, corresponding to an integrated luminosity of 5.4 fb$^{-1}$ and collected by the LHCb experiment during LHC Run 2, is used to measure the ratio of the lifetime of the ${\it{\Xi}}_b^0$ baryon to that of the ${\it{\Lambda}}_b^0$ baryon, $r_{\tau}\equiv\tau_{{\it{\Xi}}_b^0}/\tau_{{\it{\Lambda}}_b^0}$. The value ${r_{\tau}^{\rm Run\,2}=1.004\pm0.009\pm0.006}$ is obtained, where the first uncertainty is statistical and the second systematic. [...]

First observation of the $\mathit{\Lambda}_b^{0}\!\rightarrow\mathit{\Lambda}_{c}^{+}D_{s}^{-}K^{+}K^{-}$ decay and search for pentaquarks in the $\mathit{\Lambda}_{c}^{+}D_{s}^{-}$ system / LHCb Collaboration
The $\mathit{\Lambda}_b^{0}\!\rightarrow\mathit{\Lambda}_{c}^{+}D_{s}^{-}K^{+}K^{-}$ decay is observed for the first time using the data sample from proton-proton collisions recorded at a center-of-mass energy of $13\,\text{TeV}$ with the LHCb detector, corresponding to an integrated luminosity of $6\,\text{fb}^{-1}$. The ratio of branching fraction to that of $\mathit{\Lambda}_b^{0} \!\rightarrow\mathit{\Lambda}_{c}^{+}D_{s}^{-}$ decays is measured as $0.0141 \pm 0.0019 \pm 0.0012$, where the first uncertainty is statistical and the second systematic.
