This paper describes a search for beyond the Standard Model decays of the Higgs boson into a pair of new spin-0 particles subsequently decaying into $b$-quark pairs, $H\ensuremath{\rightarrow}aa\ensuremath{\rightarrow}(b\overline{b})(b\overline{b})$, using proton-proton collision data collected by the ATLAS detector at the Large Hadron Collider …

Abstract Cross-sections of associated production of a Higgs boson decaying into bottomquark pairs and an electroweak gauge boson, W or Z, decaying into leptons are measured as a function of the gauge boson transverse momentum. The measurements are performed in kinematic fiducial …

ATLAS measurements of the production of muons from heavy-flavor decays in $\sqrt{{s}_{NN}}=2.76$ TeV Pb+Pb collisions and $\sqrt{s}=2.76$ TeV $pp$ collisions at the LHC are presented. Integrated luminosities of 0.14 ${\mathrm{nb}}^{\ensuremath{-}1}$ and 570 ${\mathrm{nb}}^{\ensuremath{-}1}$ are used for the Pb+Pb and $pp$ measurements, respectively, …

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 …
