Search for heavy neutral leptons in decays of $W$ bosons produced in 13 TeV $pp$ collisions using prompt signatures in the ATLAS detector / ATLAS Collaboration
The existence of right-handed neutrinos with Majorana masses below the electroweak scale could help address the origins of neutrino masses, the matter-antimatter asymmetry, and dark matter. [...]

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.

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.
