Measurements of differential cross sections for $J/\ensuremath{\psi}$ production in $p+\mathrm{Pb}$ collisions at $\sqrt{{s}_{NN}}=5.02$ TeV at the CERN Large Hadron Collider with the ATLAS detector are presented. The data set used corresponds to an integrated luminosity of $28.1 {\mathrm{nb}}^{\ensuremath{-}1}$. The $J/\ensuremath{\psi}$ mesons are …

A search is presented for production of dark-matter particles recoiling against a leptonically decaying $Z$ boson in $20.3\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of $pp$ collisions at $\sqrt{s}=8\text{ }\text{ }\mathrm{TeV}$ with the ATLAS detector at the Large Hadron Collider. Events with large missing transverse momentum …

A measurement of the parity-violating decay asymmetry parameter, ${\ensuremath{\alpha}}_{b}$, and the helicity amplitudes for the decay ${\mathrm{\ensuremath{\Lambda}}}_{b}^{0}\ensuremath{\rightarrow}J/\ensuremath{\psi}({\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}){\mathrm{\ensuremath{\Lambda}}}^{0}(p{\ensuremath{\pi}}^{\ensuremath{-}})$ is reported. The analysis is based on 1400 ${\mathrm{\ensuremath{\Lambda}}}_{b}^{0}$ and ${\overline{\mathrm{\ensuremath{\Lambda}}}}_{b}^{0}$ baryons selected in $4.6\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of proton--proton collision data with a center-of-mass energy …
