Exclusive dimuon production in ultraperipheral collisions (UPC), resulting from photon-photon interactions in the strong electromagnetic fields of colliding high-energy lead nuclei, $\mathrm{PbPb}(\ensuremath{\gamma}\ensuremath{\gamma})\ensuremath{\rightarrow}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}({\mathrm{Pb}}^{(★)}{\mathrm{Pb}}^{(★)})$, is studied using ${\mathcal{L}}_{\mathrm{int}}=0.48\phantom{\rule{4pt}{0ex}}{\mathrm{nb}}^{\ensuremath{-}1}$ of $\sqrt{{s}_{NN}}=5.02\phantom{\rule{4pt}{0ex}}\text{TeV}$ lead-lead collision data at the LHC with the ATLAS detector. Dimuon pairs are measured …

Two-particle long-range azimuthal correlations are measured in photonuclear collisions using $1.7\phantom{\rule{4pt}{0ex}}{\mathrm{nb}}^{\ensuremath{-}1}$ of 5.02 TeV $\mathrm{Pb}+\mathrm{Pb}$ collision data collected by the ATLAS experiment at the CERN Large Hadron Collider. Candidate events are selected using a dedicated high-multiplicity photonuclear event trigger, a combination of …

Combined measurements of Higgs boson production cross sections and branching fractions are presented. The combination is based on the analyses of the Higgs boson decay modes $H\ensuremath{\rightarrow}\ensuremath{\gamma}\ensuremath{\gamma}$, $Z{Z}^{*}$, $W{W}^{*}$, $\ensuremath{\tau}\ensuremath{\tau}$, $b\overline{b}$, $\ensuremath{\mu}\ensuremath{\mu}$, searches for decays into invisible final states, and on measurements …

Abstract To assess the properties of the quark–gluon plasma formed in ultrarelativistic ion collisions, the ATLAS experiment at the LHC measures a correlation between the mean transverse momentum and the flow harmonics. The analysis uses data samples of lead–lead and proton–lead collisions …

A search for four-top-quark production, $t\overline{t}t\overline{t}$, is presented. It is based on proton-proton collision data with a center-of-mass energy $\sqrt{s}=13\text{ }\text{ }\mathrm{TeV}$ collected by the ATLAS detector at the Large Hadron Collider during the years 2015 and 2016, corresponding to an integrated …

Results of a search for the pair production of photon-jets---collimated groupings of photons---in the ATLAS detector at the Large Hadron Collider are reported. Highly collimated photon-jets can arise from the decay of new, highly boosted particles that can decay to multiple photons …

A search for supersymmetry in events with large missing transverse momentum, jets, and at least one hadronically decaying $\ensuremath{\tau}$-lepton is presented. Two exclusive final states with either exactly one or at least two $\ensuremath{\tau}$-leptons are considered. The analysis is based on proton-proton …

A measurement of the rapidity and transverse momentum dependence of dijet azimuthal decorrelations is presented, using the quantity ${R}_{\mathrm{\ensuremath{\Delta}}\ensuremath{\phi}}$. The quantity ${R}_{\mathrm{\ensuremath{\Delta}}\ensuremath{\phi}}$ specifies the fraction of the inclusive dijet events in which the azimuthal opening angle of the two jets with the …

Previous studies have shown that weighted angular moments derived from jet constituents encode the colour connections between partons that seed the jets. This paper presents measurements of two such distributions, the jet-pull angle and jet-pull magnitude, both of which are derived from …
